Question

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

P(x) = -x⁴ + 6x³ + 2x² - 10x - 8 ; P(2)

Please show full work, thanks! (:

Answer 1

-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

Answer 2

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
`p`=
`- x^(4) + 6x^(3) + 2x^(2) -10x-8` substitute x with 2.

Step #2


`= -2^(4) +6 * 2^(3) +2*2^(2) -10*2-8=12`

Your final answer SHOULD be
`\boxed{12}`

I hope this can help you.
