Question

kx³+8x²-4x+10 divided by (x+1) leaves the remainder -3, then the value of k​

Answer 1

Answer:

-21

Step-by-step explanation:

p(x) = kx^3 + 8x^2 - 4x + 10

The factor of (x+1) = -1

p(-1) = k(-1)^3 + 8(-1)^2 - 4(-1) + 10 = 0

= -1k + 8 + 4 +10 = 0

= 8 + 4 + 10 = 1k

= 22. = 1k

= k. = 1 - 22

= k. = -21
