v^2+v-300=0

Solution for v^2+v-300=0 equation:

v^2+v-300=0

a = 1; b = 1; c = -300;
Δ = b2-4ac
Δ = 12-4·1·(-300)
Δ = 1201
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$v_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(1)-\sqrt{1201}}{2*1}=\frac{-1-\sqrt{1201}}{2}
$
$v_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(1)+\sqrt{1201}}{2*1}=\frac{-1+\sqrt{1201}}{2}
