Question

The polynomial p(x) = kx³ + 9x² + 4x -8 when divided by (x-3) leaves a remainder 10(1-k) . Find the value of k.

Answer 1

Answer:

which class are you in ?

Step-by-step explanation:

p(x)=ku^3+9x^2+4x-10 ÷ (x-3)

remainder-22

Answer 2

$x - 3 = 0 \\ x = 3$

$27k + 9(9) + 4(3) - 8 = 10( 1- k) \\ 27k + 81 + 12 - 8 = 10 - 10k \\ 27k + 85 = 10 - 10k \\ 27k + 10k = 10 - 85 \\ 37k = 75 \\ \\ k = 75 \div 37$
