Question

Find ‘k’ if ( x - 2 ) is a factor of x^3- kx^2- 112

Answer 1

Answer:

k=-26

Step-by-step explanation:

p(x)= x³-kx²-112                                            g(x)=> x-2=0   =>x =2

p(2) => (2)³-k(2)²-112

      =>8-k4-112

     => -k4+8-112

     =>-k4-104

-k4-104=0

=> -k4 = 104

=>-k = 104/4

=>k = -26
