Question

Find the value of the polynomial p(x) = 2x^3–4x^2 + 5x + 1 when x = –2 .

Answer 1

Here we go ⬇️

2x³-4x²+5x+1

2(-2)³-4(-2)²+5(-2)+1

-16-16-10+1

=-32-9

= -41

follow me ✌️

Answer 2

Step-by-step explanation:

p(-2)=2×(-2)³-4(-2)²+5×(-2)+1

=2×(-8)-4×4-10+1

= -16-16-9

= -41

p(x)= -41
