Question

Find the value of K, if Kx3+9 x² + 4x-10 is divided
by (x+ 3) Leaves a remuder -22​

Answer 1

Answer:

k=3

Step-by-step explanation:

When p(x) is divided by (x-a), the remainder is p(a)

Remainder when $kx^{3}+9x^{2}+4x-10$ is divided by x+3

=-27k+81-12-10=-22  (given)

=>  -27k+81=0

=>   k=3
