Question

If f(x)=2x2+3x−4, and g(x)=−8x−4, what does f(x)+g(x) equal?

Answer 1

2x² - 5x - 8

Explanation:

f(x) + g(x)

= (2x²+3x−4) + (−8x−4)

= 2x² - 5x - 8

Answer 2

2x^2 -5x -8

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
