Question

The value of p for which the polynomial x 3 + 4 x 2 – p x + 8 is exactly divisible by ( x – 2 ) is:

Answer 1

Answer:

answer is 16

Step-by-step explanation:

p(x)=x^2+4x^2-px+8 is divisible exactly by (x-2)

x=2 is zero of p(x)

hence p(2)=0

2^3+4×2^2-p×2+8=0

8+16+2p+8=0

2p=32

p=32/2

p=16

Answer 2

HERE IS YOUR ANSWER MATE.....;

$= > p = 16$
