Question

Using the quadratic formula, which of the following is the solution to the quadratic equation below? 5x^2+7×+3=0

Answer 1

$\begin{gathered} 5x^2+7x+3=0 \\ x=\frac{-7\pm\sqrt[]{7^2-4\times5\times3}}{2\times5} \\ x=\frac{-7\pm\sqrt[]{49-60}}{10} \\ x=\frac{-7\pm i\sqrt{11}}{10} \\ x=\frac{-7}{10}\pm\frac{i\sqrt[]{11}}{10} \end{gathered}$
