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*5*3}}{2*5} \\ x=\frac{-7\pm\sqrt[]{49-60}}{10} \\ x=(-7\pm i√(11))/(10) \\ x=(-7)/(10)\pm\frac{i\sqrt[]{11}}{10} \end{gathered}`
