Question

How can we solve a quadratic inequality by factorizing it?

Answer 1

You can factorize the inequality by bringing all terms to LHS, then factorizing it into two linear binomials and finally using sign chart.

Explanation:

You can factorize the inequality (not necessarily a quadratic) by bringing all terms to LHS, then factorizing it into two linear binomials and finally using sign chart.
