To simplify the expression 2a^2b^2 + 5ab^2 + 8a^2b^2 - 3ab^2, first combine like terms. The terms with a^2b^2 are 2a^2b^2 + 8a^2b^2 = 10a^2b^2. The terms with ab^2 are 5ab^2 - 3ab^2 = 2ab^2. Therefore, the simplified expression is 10a^2b^2 + 2ab^2.
associative property
x2+bx+ax+ab = x2+ax+bx+ab = x(x+a)+b(x+a) = (x+a)(x+b)
3x6 and 4x4. Solution got from: assume adjacent sides are a and b. Then (2a+2b)=ab. Multiply both sides by 2/(ab) to get 1/a + 1/b = 1/2 and the solution is obvious (if it wasn't in the first place).
