8v^2-63v-8=0
a = 8; b = -63; c = -8;
Δ = b2-4ac
Δ = -632-4·8·(-8)
Δ = 4225
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{4225}=65$$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-63)-65}{2*8}=\frac{-2}{16} =-1/8 $$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-63)+65}{2*8}=\frac{128}{16} =8 $
