Neither does my TI-89 Titanium. There is no simple factoring for this expression.

What is rational expression of (22x +11) (10x2 +5x)


I assume the 10x2 means 10 squared. (I will show it as 10x**2)
(22x+11)(10x**2+5x) factors into"
11(2x+1)*5(2x**2+1x)
=55(2x+1)(2x**2+1x)
=(55x)(2x+1)(2x+1)
Multiplied out, it becomes 55x(4x**2+4x+1)
= 220x**3 + 220x**2 + 55x

5[x(2+y)] What is the associative law to of addition to this expression?


5[x(2+y)] What is the associative law to of addition to this expression? Wrong forum category but... The associative law of addition does just that: it associates some factor (some multiplier) in an expression with all of the terms in string of addends by which the factor will be multiplies. I na nutshell, the laws holds, for example, that in the expression, 5[x(2+y)], the factor, x, can be multiplied by each term of the sum (2+y), without first finding their total, to arrive at (2x + yx); and, in turn, those terms can be separately associated again with the factor, 5, in order to arrive at the equation,
5(2x + yx) = 10x + 5xy. Note also that the law includes its reverse, by which terms can be dissociated and summed prior to being multiplied by a former distributed factor.

6x squared - 10x =0


Factor out 3X
3X(2X-5)=0
The expression is equal to zero if one of the factors on the left side equals zero.
1st solution: 3X=0, thus X=0
2nd solution 2X-5 = 0 if X=5/2

How do you get a factoring program onto this calculator, that could factor 3 terms? Like X^2 2X - 3 = (X - 1) (X 3)


There are several factoring programs available at

How do I solve x and y in the following equations? 5x+3y=6 2x-4y=5 Thank you


You can solve it with following method.

5x+3y=6 2x-4y=5
So 5x=6-3y so 2[(6-3y)/5]-4y=5
So x=(6-3y)/5 so 12-6y-20y=25
so -26y=25-12
so -26y=13
so y= -(1/2)
2x-4y=5
so 2x=5+4y
so 2x=5+4(-1/2)
so 2x=(10-4)/2
so 2x=6/4
so x =3/2

The value of x=3/2 and value of y= -1/2

Let me know if you need further assistance.
Thanks for using FixYa.

Find the value of the variable ''x'' 6x+6=4x+12


6x+6=4x+12
Since 4x contains the variable to solve for, move it to the left-hand side of the equation by subtracting 4x from both sides.
6x+6-4x=12
Since 6x and -4x are like terms, add -4x to 6x to get 2x.
2x+6=12
Since 6 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 6 from both sides.
2x=-6+12
Add 12 to -6 to get 6.
2x=6
Divide each term in the equation by 2.
(2x)/(2)=(6)/(2)
Simplify the left-hand side of the equation by canceling the common factors.
x=(6)/(2)
Simplify the right-hand side of the equation by simplifying each term.
x=3

Good Luck

Inputing factors on a casio fx-115es calculator


Unless I am failing to understand your problem, just combine like terms to get:
9x^2+2x+4 and then enter those coefficients into the quadratic solver.
That will get you the two answers -- both of them will be complex.
If you wanted to turn those two answers into factors (complex) of the original equation simply
change the signs on each and put an x in front.
Of course, the quadratic formula would also work.
