Question

Please answer my question Please please
If -3/2 is a zero of polynomial p(X)=2x^3+9x^2-x-a
Find value of a

Answer 1

one root is given

x = -3/2

substituting in the equation

2(-3/2)^3 + 9(-3/2)^2 - (-3/2) -a = 0

-27/4 + 81/4 + 3/2 - a = 0

(81-27)/4 + 3/2 - a = 0

27/2 + 3/2 - a

a = 15

hope it helped you

Answer 2

Answer:

The value of a will be 15
