Question

Find a if x+2 is a factor of 4xpower3 -6x power2 +8a-10​ anyone please tell it is so important​

Answer 1

Answer:

Here is your answer

Step-by-step explanation:

Given - Factor = (x+2)

P(x) = 4x^3 - 6x^2 + 8a - 10

x = -2

P(-2) = 4 x (-2)^3 - 6 x (-2)^2 + 8a - 10

P(-2) = -32 - 24 + 8a - 10

P(-2) = -66 + 8a

0 = -66 + 8a

66 = 8a

8.25 = a
