# Steps to solve a Quadratic Inequalities

Step to solve a Quadratic Inequalities

Step 1 : Rewrite the inequality with zero on one side and make sure a > 0
Step 2 : Find where it crosses the x-axis  (Put y=0)
Step 3 : Sketch the graph and shade the region to find the range of values of  x

Example

Find the range of values of x for each of the following :

(a)${x}^{2}-4x+3<0$
(b)$12+10x-2{x}^{2}<0$
