Question

Find the value of k if the division of kx cube plus 9x square plus 4x minus 10 by x plus 3 leaves a remainder -22

( please answer this in detail ) ​

Answer 1

Answer:

If you are dividing by x+3 then take x+3=0 or x=-3

put this value of x in the polynomial

k(-3)^3 + 9(-3)^2 +4(-3) -10 = -22

-27k + 81 -12-10=-22

-27k = -81

k=81/27=3 Ans
