Question

check whether y
x-4 is a factor of x³-3x²-6x+8 or not.
​

Answer 1

Answer:

Here you go!

Step-by-step explanation:

p(x)=x³-3x²-6x+8

g(x)= x-4

         x-4= 0

       x=4

Substitute the value of x in the polynomial:

p(4)= (4)³-3(4)²-6(4)+8

     = 64-48-24+8

     =  0

Therefore x-4 is a factor of x³-3x²-6x+8
