Consider the following functions. Perform the operations to determine the values of a, b, c, d, and e. part a: f(x)=(x^2+7x-12) and g(x)=(x^2-9x+1) f(x)•g(x)=ax^4-bx^3-cx^2+dx-e part b: h(x)=(x^2+2) and k(x)=(2x^2-5x+7) h(x)•k(x)=ax^4-bx^3-cx^2+dx-e

you answer is a

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
