Which of the following is algebraically equivalent to the sum of 4x^2 -8x +7 And 3x^2-2x-5

VARVARA [1.3K]

All you have to do, is combine like terms. Let's go through it:

$(4x^2-8x+7)+(3x^2-2x-5)$

Arrange it so you can easily combine like terms:

$4x^2+3x^2-8x-2x+7-5 = 7x^2-10x+2$

So, your answer for the sum is 1) 7x² - 10x + 2
