Solving a quadratic inequality in Algebra is similar to solving a quadratic equation. The only exception is that, with quadratic equations, you equate the expressions to zero, but with inequalities, you’re interested in knowing what’s on either side of the zero i.e. negatives and positives.
Quadratic equations can be solved by either the factorization method or by use of the quadratic formula. Before we can learn how to solve quadratic inequalities, let’s recall how quadratic equations are solved by handling a few examples.
Answers & Comments
Answer:
f quadratic inequalities are: x2 – 6x – 16 ≤ 0, 2x2 – 11x + 12 > 0, x2 + 4 > 0, x2 – 3x + 2 ≤ 0 etc.
