Which expression is equivalent to (x2+7x-11)-(-5x2+2x-2)?
Which expression is equivalent to (x2+7x-11)-(-5x2+2x-2)?
6x2+5x-13
-4x2+9x-13
6x2+5x-9
-4x2+5x-9
(x2+7x-11)-(-5x2+2x-2) simplifies to:
x^2 + 7x - 11 + 5x^2 - 2x + 2
Combining like terms, we get:
6x^2 + 5x - 9
Therefore, the expression that is equivalent to (x^2+7x-11)-(-5x^2+2x-2) is 6x^2 + 5x - 9.
