Sounds easy enough. DO you know the Quadratic formula?

\[4x^{2}+9x+20\] I know that the answer is: \[x=\frac{ 9\pm \sqrt{814(4)(2)} }{ 8 }\]

ik but, i don't get how you got them. how do you go from\[9\pm \frac{ \sqrt{8132} }{ 8 } \to 9\pm \frac{\sqrt{49} }{ 2 } \]

For \[ax^2+bx+c=0=4x^2+9x+2\] \[a=4,b=9,c=2\] using the quadratic formula \[x=\frac{b\pm \sqrt{b^24ac}}{2a}\] substituting in \[a=4,b=9,c=2\] \[x=\frac{9\pm \sqrt{9^24(4)(2)}}{2(4)}\] \[x=\frac{9\pm \sqrt{8132}}{8}\] \[x=\frac{9 \pm \sqrt{49}}{8}\] \[x=\frac{9\pm 7}{8}\] \[x=\frac{9+7}{8}\] \[x=\frac{2}{8}=\frac{1}{4}\] and \[x=\frac{97}{8}\] \[x=\frac{16}{8}=2\]
