Question

Ho do you solve this?
Find p(2) for p(x) = x4 + 3x3 - 2x2 - 4x + 1.

Answer 1

Substitute 2 for every 'x' in the equation.Solve.

Answer 2

I tried that but im not getting the right answer i keep getting 209 what am i doing wrong?

Answer 3

as DYHW has stated....for every 'x' you see in your equation....replace it with a (2)

so you have

\[(2)^4 + 3(2)^3 -2(2)^2 - 4(2)+ 1\]

and solve

you get

16 + 24 - 8 - 8 + 1
40 - 16 + 1
24 + 1
25 is what I get
