            <h2>Solving Quadratics</h2>
            <p>Click START to generate a random quadratic equation to solve.</p>
            <p>All answers should be in lowest terms and simplest radical form.  That means if you get an answer like:</p>
            <p>\(x=\frac{28\pm\sqrt{320}}{12}\)</p>
            <p>It is really:</p>
            <p>\(x=\frac{28\pm\sqrt{320}}{12}=\frac{28\pm8\sqrt{5}}{12}=\frac{4(7\pm2\sqrt{5})}{4(3)}=\frac{7\pm2\sqrt{5}}{3}\)</p>
            <p>And should be typed it as <b>(2+√2)/3</b> as the solution for \(x_1\) and <b>(2+√2)/3</b> for \(x_2\).  Note that you need the parentheses around the numerator.</p>
            <p>If you type "sqrt", it will be replaced with √, and if you type "no", it will be replaced with ∅ to represent no solution.  If there is only one solution, put the ∅ as the solution for \(x_2\).</p>

                <h3>Best Methods Based on Type of Quadratic</h3>
                <ul>
                    <li><b>Standard Form:</b> \(ax^2+bx+c=0\)
                        <br/>▹Try factoring or graphing first<br/>
                        <br/>▹If that doesn't work, use the quadratic formula: \(x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\)<br/><br/></li>
                    <li><b>Vertex Form:</b> \(a(x-h)^2+k=0\)
                        <br/>▹Use inverse operations</li>
