Question

What is the next step to find all the roots of a quadratic equation which has been factorized?

• A. Equate the first factor to 0
• B. Equate both factors to 1
• C. Equate both factors to 0
• D. Can't say

Answer 1

The correct option is C

Equate both factors to 0

If $a\times b=0$, it could mean that $a=0$ or $b=0$ or both of them are zero. To find all the roots, both the factors must be made equal to zero.
