#### Question

Solve the following quadratic equations by factorization:

(*x* − 4) (*x *+ 2) = 0

#### Solution

We have

(*x* − 4) (*x *+ 2) = 0

either

⇒ (*x* − 4) = 0 or (*x *+ 2) = 0

⇒ x = 4 or x = -2

Thus, x = 4 and x = -2 are two roots of the equation (*x* − 4) (*x *+ 2) = 0

Is there an error in this question or solution?
