2x^25x10=0 Quadratic Formula \[x=\frac{b\pm\sqrt{b^24ac}}{2a}\] a=2 b=5 c=10 \[x=\frac{5\pm\sqrt{25+80}}{4}=\frac{5\pm\sqrt{105}}{4}\]

\[2x^2  5x  10 =0 \] We know the quadratic formula is of the form... \[x = \frac{b \pm \sqrt{(b^24ac)}}{2a} \] Let's try to determine what these variables correspond to in our given equation. \[ a = 2\\b = 5\\c = 10 \] So, now we can plug and solve. \[x = \frac{5 \pm \sqrt{(25+80)}}{4} \]
