Cindy · Answer 1

2x² - 5x - 8

Step-by-step explanation:

f (x) + g (x)

= (2x²+3x-4) + (-8x-4)

= 2x² - 5x - 8

Mario Pierce · Answer 2

2x^2 - 5x - 8

Step-by-step explanation:

f (x) = 2x^2+3x-4,

g (x) = -8x-4,

f (x) + g (x) = 2x^2+3x-4 + - 8x-4

Combine like terms

= 2x^2 + 3x - 8x - 4-4

=2x^2 - 5x - 8
