Question

find the value of k if the remainder is -3 when k x cube + 8 x square - 4 x + 10 is divided by X + 1​

Answer 1

Answer:

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

If, g(x) = x+1,then. x=-1

Step-by-step explanation:

by putting this value of.x.in the above equation,

k(-1) + 8(1) - 4 + 10 = -3

-k + 8 - 4 + 10 = -3

transposing the whole numbers to RHS

-k = -8 +4 -10 -3

-k = -4 -13

-k=-17

Cancelling minus from both sides,

k = 17

The correct value of k is 17
