The answer is x= −1,4,2.

How to solve the equation?

Factor the left side of the equation.

(x+1)(x−4)(x−2)=0

If any individual factor on the left side of the equation is equal to 0

, the entire expression will be equal to 0.

⇒ x+1 = 0

⇒ x−4 = 0

⇒ x−2 = 0

Set the first factor equal to 0 and solve.

⇒ x = −1

Set the next factor equal to 0 and solve.

x=4

Set the next factor equal to 0 and solve.

x=2

The final solution is all the values that make

⇒ (x+1)(x−4)(x−2) = 0 true.

⇒ x= −1,4,2.
