Hello,
You have the method: apply it.
2 *(3x-4)(4x+5) =(6x-8)(4x+5)
Now apply the FOIL method
F: 6x*4x=24x^2
O: 6x*5=30x
I; -8*4x=-32x
L: -8*5=-40

so the result is
24x^2 + 30x-32x -40 =24x^2 -2x-40

Demonstrate how to multiply two binomials


Try to seek these: By using the suggested format:
Suggested su
  1. Adding and Subtracting Binomials
    • 1

      Arrange each term in each binomial in order of degree from greatest to least. The degree of a binomial is the exponent attached to the term. For example, 4x^2 is a second degree term.

    • 2

      Multiply each term in the binomial that is being subtracted by -1 to turn it into an addition problem. For example, the problem (8x^2 + 8) - (x^2 - 2) becomes (8x^2 + 8) + (-x^2 + 2).

    • 3

      Combine like terms. In the example problem, the x^2 terms are combined and the constant terms are combined, yielding (8x^2 + 8) + (-x^2 + 2) = 7x^2 + 10.

    Multiplying Binomials
    • 4

      Understand the F.O.I.L. method. F.O.I.L. is an acronym standing for first, outside, inside and last. It means that you multiply the first number of the first binomial by the first number of the second, then the numbers on the outside (the first term of the first binomial by the second term of the second binomial) and so on. This ensures that both numbers in the first binomial are multiplied by both numbers in the second.

    • 5

      Use the F.O.I.L. method to multiply the two binomials together. For example, (3x + 4)(3x - 4) = 9x^2 +12x - 12x - 16. Notice that -12x is the product of the outside terms and -16 is the product of the last terms, 4 and -4.

    • 6

      Simplify. There will almost always be like terms to combine. In the example, 12x and -12x cancel out, yielding the answer 9x^2 - 16.

    Dividing Binomials
    • 7

      Use the distributive property to divide both terms in the binomial by the monomial divisor. For example, (18x^3 + 9x^2) / 3x = (18x^3 / 3x) + (9x^2 / 3x).

    • 8

      Understand how to divide by a term. If you are dividing a higher order term by a lower order term, you subtract the exponent. For example, y^3/y = y^2. The number part of each term is handled like any other division problem. For example, 20z / 4 = 5z.

    • 9

      Divide each term in the binomial by the divisor; (18x^3 / 3x) + (9x^2 / 3x) = 6x^2 + 3x.

How to solve foil method


The FOIL Method is a process used in algebra to multiply two binomials. The lesson on the Distributive Property, explained how to multiply a monomial or a single term such as 7 by a binomial such as (4 + 9x).
1.gif But, what if there was a binomial instead of a single term outside of the parentheses? That is, what if a binomial was being multiplied by another binomial? An example of this is given below.
2.gif
FOIL stands for:
First - Multiply the first term in each set of parentheses Outer - Multiply the outer term in each set of parentheses Inner - Multiply the inner term in each set of parentheses Last - Multiply the last term in each set of parentheses Now let's give it a try in our problem. We'll start by multiplying the first term in each set of parentheses and then marking down the answer below the problem.
3.gif Now we will multiply the outer terms and again mark down the answer below the problem.
4.gif And the Inners.
5.gif And finally the last terms.

Tin foil stuck to bottom of oven how to remove it


See this link: http://askruth.blogspot.com/2006/07/cleaning-baked-on-foil-in-oven-help.html

"I called Sears and this is what they said to do:

BE CAREFUL, remove as much of the foil as possible Turn oven on to 200 lay an old wet bath towel on top. Use a plastic spatular to remove the foil.

They said it will take some time to remove the foil, in some cases days, and that you can still use the oven but DO NOT use the self cleaning untill all the foil is removed."

If you can remove the bottom drip tray/pan from your oven which the tinfoil is stuck to, than remove it. Ovens with "hidden element" usually have the removable bottom tray/pan. Don't scrape yet!!
Lay the tinfoil laden tray on a flat service where it wont be disturbed for a couple of days.
Now remove any tinfoil you can with a plastic scraper/spatula/pancake flipper.
Once thats done, pour bleach directly onto the drip tray/pan until it covers all the stuck tinfoil.(assuming your oven pan is like mine and has a lip all the way around and is somewhat countersunk).
Leave the bleach in for about 2 days. Now get your plastic scraper again and scrape away. The stuck tinfoil should all be dissolved by the bleach and the scraper should get rid of any residue. Then rinse!
Now this method will probably leave some darkened stains on the oven tray, but not near as ugly or noticeable as that melted tinfoil!!

Good luck!!
