Question

#6 Solve each with quadratic formula simplify in radical form if needed

Answer 1

Given:

`11v^2+8v=4`

Sol:.

`\begin{gathered} 11v^2+8v=4 \\ 11v^2+8v-4=0 \end{gathered}`
`\begin{gathered} x=\frac{-b\pm\sqrt[]{b^2-4ac}}{2a} \\ x=\frac{-8\pm\sqrt[]{64-4(11)(-4)}}{2*11} \\ x=\frac{-8\pm\sqrt[]{64+176}}{2*11} \\ x=(-8\pm15.49)/(22) \\ x=(-8-15.49)/(22);x=(-8+15.49)/(22) \\ x=-1.0678;x=0.340 \end{gathered}`
