Graph and solve quadratic inequalities

WebA quadratic equation uses an inequality sign instead of an equal to sign. A quadratic inequality is of the form ax2 + bx + c > 0 or ax2 + bx + c < 0. Learn about solving quadratic equations with formulas, graphs, … WebExample: Solve the inequality x^2 \lt 64. When solving quadratic inequalities it is important to remember there are two roots. If the question was solve x^2=a^2 we would simple take the square root of both sides so that x=\pm a. The range of values that satisfy the inequality is between -8 and 8. This can be expressed as,-8 \lt x \lt 8

I … WebNow we can determine the solution by looking at the graph we just plotted. Our inequality was x^2 +4x -5 &gt; 0. We know that in x = -5 and x = 1 the expression is equal to zero. We must have that the expression is larger than zero and therefore we need the regions left from the smallest root and right of the largest root. Our solution will then be:
