Step-by-step explanation:
Answer:
The correct option is C.
Step-by-step explanation:
polynomial has roots of −6, 1, and 4.
We can write it as:
(x+6)(x-1)(x-4)
Now multiply the terms:
First multiply first and second bracket:
{x(x+6)-1(x+6)}(x-4)
{(x^2+6x-x-6)} (x-4)
Solve the like terms:
{(x^2+5x-6)}(x-4)
x(x^2+5x-6) -4(x^2+5x-6)
x^3+5x^2-6x-4x^2-20x+24
Solve the like terms:
x^3+x^2-26x+24
Hence it is proved that the correct option is C....
