Question

find the value of polynomial p(x) =2+x+2x square -x cube at x=2

Answer 1

Answer:

equation is p(x) = 2+x+2x²-x³

first making equation in standard form

= -x³+2x²+x+2 or x³-2x²-x-2

Step-by-step explanation:

p(x)= x³-2x-x-2

putting value of x=2

p(2)= (2)³-2(2)²-2-2

=> p(2) = 8-8-4 => -4

so, the value is -4
