This week in Pre-Calc 11 we learned how to solve inequalities with quadratics then writing them down into interval notation. I chose this topic because it is something I especially struggled with on the skills check.

The first step in solving a quadratic inequality is to identify our equation. We can tell when a quadratic inequality is a quadratic inequality by x(squared) or 2 x variables multiplying.

Now that we know our inequality is a quadratic, our next step is to find the roots of our equation by converting it into factored form.

Giving us the x-int of the parabola we can now plot it on the line graph.
