URGENT HELP 100 POINTS! Please Show the steps!! I'm So Lost
Use synthetic division to find P(-3) for

`P\left(x\right)=-2x^{4}+6x^{2}-x`` +1`

its long b ut i hope it helps:)

SOLUTION STEPS

P(x)=(x+4)(x+2)(x−1)

Apply the distributive property by multiplying each term of x+4 by each term of x+2.

(x

+2x+4x+8)(x−1)

Combine 2x and 4x to get 6x.

(x

2

+6x+8)(x−1)

Apply the distributive property by multiplying each term of x

2

+6x+8 by each term of x−1.
