Question

Perform the indicated operation

g(a) = -3a + 1

h(a) = 3a3 + 4a

@iGreen

Answer 1

You need the solution to those two equations?

Answer 2

its said find g(n) h(n)

Answer 3

I'm not sure..sorry.

Answer 4

g(n) h(n) = ? I might be wrong, but my best guess would be to multiply them together and foil?

(-3x+1) (3a^3+4a)

do you know how to foil that @morrisd7

Answer 5

no i dont know foil

Answer 6

foil is the distributive property that includes polynomials
FOIL stands for First, Outer, Inner, Last (aka the order you multiply)
so (a+b)(c+d) = ac + ad + bc + bd

so then (-3a+1) (3a^3+4a)
= (-3a)(3a^3) + (-3a)(4a) + (1)(3a^3) + (1)(4a) can you simplify that now?

Answer 7

no

Answer 8

hmmm if you have not learned this
then are you sure it said to find "g(n) h(n)"
or was it "g(n)+h(n)" something like that?

Answer 9

yea

Answer 10

(-3a)(3a^3) + (-3a)(4a) + (1)(3a^3) + (1)(4a) becomes
-9a^4 - 12a^2 + 3a^3 + 4a
