Question

If x = 2 and x = 0 are zeroes of the polynomial 2x3

- 5x2+ px + b, then find the value of p and b.​

Answer 1

Answer:

2(2^3)-5(2^2)+2p+b=0

16-20+2p+b=0

2p+b=4. This is first equation

2(0^3)-5(0^2)+p(0)+b=0

0-0+0+b=0

Therefore b=0

Substitute in First equation

2p+b=4

2p+0=4

P=4/2

Therefore p=2
