Question

Verify whether 2 is the zero of the polynomial P(x)=2x3
- px
2+17x-6 if p is 11.

Answer 1

Answer:

Yes

Step-by-step explanation:

If 2 is the zero of the polynomial p(x) then p(2) = 0

Given => p(x) = 2x³-px²+17x-6

if p = 11 then p(x) = 2x³-11x²+17x-6

let x = 2 then

p(2) = 2(2)³-11(2)²+17(2)-6 = 16-44+34-6 = 0

therefore 2 is the zero of the polynomial

Hence verified
