Step-by-step explanation:
3x^3-18x^2-24x+3x^2-6x-8
3x^3-15x^2-30x-8
is the required answer for your question

The answer is d because it is
The answer is x = 3 or x = -8.
Let's solve your equation step by step.
Step 1 - Factor left side of equation
(x - 3)(x + 8)=0
Step 2 - Set factors equal to 0.
x - 3 = 0 or x + 8 = 0
x = 3 or x = -8
Okay so in this question it says to solve f(7). This means to plug in the 7 every where you see an x, so that it looks like this: 
Then you'll solve it like a normal equation.
Hope this helped! Let me know if there is anything I need to clarify or explain more in depth!
