Question

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

Answer 1

x = 0, 6, -1

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.
