Question

if the polynomial 4x³-16x²+ax+7 is exactly divisible by (x-1), then find the value of a. hence factorise the polynomial ​

Answer 1

Answer:

a=5

Step-by-step explanation:

=> 4x^3-16x^2+ax+7=0

--> here this polynomial divided by (x-1) so here x=1

we should substitute x value in the given polynomial

=> 4-16+ax+7=0

=> 11-16=-a

=> -5=-a

=> a=5
