Question

if X + 1 is a factor of a x ka Cube + Mein x square - 2 X + 4 a - 9 then find value of a​

Answer 1

Step-by-step explanation:

let g(x) = x+1

let p(x) = x³+2x²-2x+4a - 9

Put g(x) = 0

We get x = -1

Put in p(x)

(-1)³+2(-1)²-2(-1)+4a- 9 = 0

-1 + 2 + 2 + 4a - 9 = 0

-10 + 4a = 0

4a = 10

a = 10/4

a = ⁵/2
