Question

Yet another one (xD). Let f(x) = x^2 + 3x - 4 and g(x) = x + 5. Find f(x) · g(x)?

Answer 1

-Options-
\[x^3 + 3x^2 + 16x - 20\]
\[x^3 + 5x^2 + 14x - 20\]
\[x^3 + 8x^2 + 11x - 20\]
\[x^3 + 9x^2 + 19x - 20\]

Answer 2

My only problem with this equation is that I don't know how to solve f(x) and g(x) equations

Answer 3

@LaceyLeanne @Jonathan..

Answer 4

There doesn't seem like there's a possible way @Smores
I would just plug in your choices, Honestly.

Answer 5

Answer 9

@divu.mkr Could you tell me how you got that answer though..?

Answer 10

no prob at all

Answer 11

yeh..you can see all x^2 coeff are diff.. just multiply those terms who can give you x^2
