Question

If 1 and -1 are zeroes of the polynomial p(x) =ax3 + x 2 − 2x + b, find the Values of a and b?

Answer 1

Answer:

a= -1 , b=04

Step-by-step explanation:

we have

$x = - 1$

$x = 1$

firstly we take x= -1

then we get

b - a = 1

again we take x=1

then we get

b + a = -1

from adding both the equation we get

b = 0

putting b=0 in any of the equation , we get

a = - 1
