Question

f(x)=x^3-5x^2-6x what does x equal

Answer 1

Answer:

x = 0, 6, -1

Step-by-step explanation:

We need to set f(x) = 0 to find the values of x for this expression.

So

$x^3-5x^2-6x=0$

We will factor out an x and do middle term factorization to arrive at our answer for x (there will be 3 x values):

$x^3-5x^2-6x=0\\x(x^2-5x-6)=0\\x(x-6)(x+1)=0\\x=0,6,-1$

These are the 3 values for x.
