Answer 3

Have you any experience with synthetic division? If you have, that's the way to go here.

Taking the supposed root and the coefficients of the polynomial, you'd start with
____________________
-2 / 2 5 7 -4
-----------------

If you're able to do this, then the final number you write will be under the line under the -4 ; it represents the value of the function when a=-2.

Answer 4

Division? Don't I have to plug in \[a\]
to the equation?

Answer 5

Wouldn't I get this? \[2(-2)^{3}+5(-2)^{2}+7(-2)-4\]

Answer 6

yup, you are right

Answer 7

Ok thanks! So my final answer is P(a) = -14 right?

Answer 8

yes
