Question

If f(x) = x^2 − 3x − 4 and g(x) = x^2 + x, what is (f + g)(x)?

Answer 1

If f(x) = x^2 − 3x − 4 and g(x) = x^2 + x, what is (f + g)(x)?

Line up f(x) and g(x), g(x) below f(x), and then add like terms together.

f(x) = x^2 − 3x − 4
g(x) = x^2 + x

Answer 2

Thanks! It told me the answer was
2x^2-2x-4
2(x^2-x-2)

Answer 3

Looks good. Be sure to label your result: (f+g)(x) =2( ... ).

Answer 4

Okay! Thank you!
