Question

If two of the zeroes of the polynomial
X3+2x2-x-2 are 1 and -1, then find the other zero of the polynomial. *​

Answer 1

Step-by-step explanation:

given two zeroes = 1 and -1

it means it will be( x+1)(x-1) =0

= x^-1 ( as the above eq is in the form of (a+b) (a-b)= a^2-b^2)

divide the main eq x³+2x²-x-2 by x²-1 u will get the quotient and the remainder

solve the eq by divident = divisor× quotient + remainder

u will get the rest two zeroes
