WebThis gives us x 2 + 4x + 1 = –2. The first thing you need to do is rearrange the inequality (equation) so it’s in the form ax 2 + bx + c = 0. All you have to do is bring the –2 to the left hand side. This gives us x 2 + 4x + 3 = 0. … WebSTEP 1: Rearrange the inequality into quadratic form with a positive squared term. ax2 + bx + c > 0 (>, <, ≤ or ≥) STEP 2: Find the roots of the quadratic equation. Solve ax2 + bx …

WebYou can use the quadratic equation to find the endpoints of the intervals that will be you solution, and would then need to test in which of those intervals the inequality is true. So in this case you could use it to find -5 and 2 [ (-3 +- Sqrt (9+4 (10)1))/2 = (-3 +- 7)/2 = -10/2 or 4/2]. This breaks up the number line into 3 intervals {x<-5 ...
