Question

polynomial 3 x cube minus 5 x square + kx - 2 and minus x cube minus x square + 7 x + K leaves the same remainder when divided by X + 2 find the value of k​

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Answer:

k=-12

Step-by-step explanation:

given:3x³-5x²+kx-2=x³-x²+7x+k

g(x)= -2

3(-2)³-5(-2)²+k(-2)-2= -( -2)³ -( -2)²+7(-2)+k

3(-8)-5(4)-2k-2= -8-4-14+k

-24-20-2-2k= -10+k

46-2k= -10+k

-46+10=2k+k

-36=3k

-36/3= -12

k= -12
