Answer:
- 16
Step-by-step explanation:
Evaluate f(2) by substituting x = 2 into f(x) , that is
f(2) = 3(2) - 3 = 6 - 3 = 3
Evaluate g(- 1) by substituting x = - 1 into g(x) , that is
g(- 1) = 8 - (- 1)² = 8 - 1 = 7
Thus
4f(2) - 4g(- 1)
= 4(3) - 4(7)
= 12 - 28
= - 16

Step-by-step explanation:
<u>Given polynomials</u>:

Factor the polynomials:
<u>Polynomial 1</u>



![\implies 3[2x(x+7)-1(x+7)]](https://tex.z-dn.net/?f=%5Cimplies%203%5B2x%28x%2B7%29-1%28x%2B7%29%5D)

<u>Polynomial 2</u>



![\implies 6[x(x+7)+2(x+7)]](https://tex.z-dn.net/?f=%5Cimplies%206%5Bx%28x%2B7%29%2B2%28x%2B7%29%5D)


The lowest common multiplier (LCM) of two polynomials a and b is the <u>smallest multiplier</u> that is <u>divisible</u> by both a and b.
Therefore, the LCM of the two polynomials is:
