Hey there,

Your question states: P(x) = -x⁴ + 6x³ + 2x² - 10x - 8 ; P(2)

For the function below, use synthetic division or substitution to find the indicated value.

Step #1

For 
[tex]p[/tex]= [tex]- x^{4} + 6x^{3} + 2x^{2} -10x-8 [/tex] substitute x with 2.

 Step #2

[tex]= -2^{4} +6 * 2^{3} +2*2^{2} -10*2-8=12[/tex]

Your final answer SHOULD be 
[tex]\boxed{12}[/tex]

I hope this can help you.

-x⁴ + 6x³ + 2x² - 10x -8

Step 1 - let the -x^4 be equal to x^4 by dividing by -1

x⁴ - 6x³ - 2x² + 10x + 8

Step 2 your going to be dividing by 2 since p= 2

That's how I do it
