Question

find f(x) times g(x)
f(x)=x^2+3x
g(x)=x+5


also if you could
f(x) times g(x)
f(x)=x^2-2
g(x)=3x

Answer 1

What would you do if it were (a+b)*(c+d)?

Answer 2

\[\bf f(g) \times g(x)=(x^2+3x)(x+5)\]Just use FOIL.

Answer 3

okay thankyou

Answer 4

does using foil apply for multiplication and division too when doing these kind of preoblems?

Answer 5

FOIL doesn't exist. Just multiply all elements of one by all elements of the other. We like to call it "Multiplication".
