Work Step by Step

Simplify equation such that the left side is the quadratic expression and the right side is $0$. Then graph the quadratic function, obtain a parabola, and find its $x$-intercepts (the $x$-coordinates of the parabola's intersection(s) with the $x$-axis). These $x$-intercepts are the solutions of the equation. If they do not exist, then the equation has no solution.
