    what about it? It's not really a problem... there is no = and no indication of which variable you are solving for.

    in A-(B-2A)

    You can simplify to 4A - B

    But it cannot be SOLVED.

3/a+1/2=11/5a how do you solve


3/a + 1/2 -> ((3*2) + (1*a)) / (a*2) -> (6 + a)/2a
so
(6 + a)/2a = 11/5a -> (6 + a)*5a/2a = 11 -> 6 + a = 11*2/5
so
a = 22/5 - 6 = 4.4 - 6 = -1.6

The sum of two is two hundred five the difference is seventy five wha is the number


Let a and b be the numbers
Sum is 205 : a+b=205
Difference is 75: a-b=75
add the two sides on the left of the = signs a+b+a-b=2a
add the two sides on the right of the = signs 205+75=280
Equate 2a and 280
2a=280
a=140
Substitute 140 for a in one of the two original equations. Take for example the first
140+b=205
b=205-140=65

Check 140+65=205 OK
a=140, b=65

(a + 2b)(a2 - 2ab - 4b2)


I believe that the algebraic expression should be written as:
(a + 2b)(a^2 - 2ab - 4b^2)

which can be rewritten as:
(a + 2b)^2 * (a - 2b)


The simplified form of this expression is:
(a^3 - 2a^2b - 4ab^2 + 2a^2b - 4ab^2 - 8b^3)

which can then be further simplified as:
(a^3 - 8b^3)

Wat is special product


Here, We deal with Some Special Products in Polynomials.

Certain products of Polynomials occur more often
in Algebra. They are to be considered specially.

These are to be remembered as Formulas in Algebra.

Remembering these formulas in Algebra is as important
as remembering multiplication tables in Arithmetic.

We give a list of these Formulas and Apply
them to solve a Number of problems.

We give Links to other Formulas in Algebra.

Here is the list of Formulas in
Polynomials which are very useful in Algebra.
Formulas in Polynomials :

Algebra Formula 1 in Polynomials:

Square of Sum of Two Terms:

(a + b)2 = a2 + 2ab + b2
Algebra Formula 2 in Polynomials:

Square of Difference of Two Terms:

(a - b)2 = a2 - 2ab + b2
Algebra Formula 3 in Polynomials:

Product of Sum and Difference of Two Terms:

(a + b)(a - b) = a2 - b2
Algebra Formula 4 in Polynomials:

Product giving Sum of Two Cubes:

(a + b)(a2 - ab + b2) = a3 + b3
Algebra Formula 5 in Polynomials:

Cube of Difference of Two Terms:

(a - b)3 = a3 - 3a2b + 3ab2 - b3 = a3 - 3ab(a - b) - b3
Algebra Formula 8 in Polynomials:


Each of the letters in fact represent a TERM.

e.g. The above Formula 1 can be stated as
(First term + Second term)2
= (First term)2 + 2(First term)(Second term) + (Second term)2

I need assistance understanding this algebra equation and the steps to solve it. 7+(9-5x)=5(2-x)


this is a simple algebraic equation in which we have to calculate the value of 'x' using simple operations

7+(9-5x)=5(2-x)


step 1(pen the brackets) 7+9-5x=10-5x
step 2(add 7 and 9) 16-5x=10-5x

now as 5x gets cancelled both the sides of the equal sign therefore no solution of this algebraic equation exist.

What is rectangular prism?


Hello
Rectangular Prism/Cuboid Definition:
A Rectangular Prism/Cuboid is a solid figure bounded by six rectangular faces, a rectangular box. All angles are right angles, and opposite faces of a cuboid are equal. It is also a right rectangular prism.

Rectangular Prism/Cuboid Formula:
Area of Base(A) = l * w
Perimeter of Base(P) = 2l + 2w
Surface Area of Prism = 2(lw) + (2l + 2w)h = 2A + Ph
Volume of Prism = lwh = Ah
Diagonal of Prism = Sqrt(l² + w² + h²)
where
l = length, w = width, h = height

Hope this helps, if so do rate the solution
