Question

For what value of a is the polynomial 2 x cube + x square + 11 x + A + 3 exactly divisible by 2 x minus 1​

Answer 1

Step-by-step explanation:

Let p(x) =

If p(x) is exactly divisible by (2x-1) then (2x-1) is a factor of p(x)

Thus p = 0

Thus p(x) is exactly divisible by (2x-1) at a = -7
