Question

If [x-2] is a factor of the polynomial find the value of a:x 5 -3x 4 -ax 3 +3ax 2 +2ax+4

Answer 1

According to the factor theorem if the zero of x-2( which is 2) the factor is put to the polynomial, then the answer of the polynomial will be zero.

So put 2 instead of x and make an equation with answer zero and find out the value of a by transporting and then put values of a and x in a:x.
