Solution for 6x2+7x-1=0 equation: 



6x^2+7x-1=0

a = 6; b = 7; c = -1;
Δ = b2-4ac
Δ = 72-4·6·(-1)
Δ = 73
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(7)-\sqrt{73}}{2*6}=\frac{-7-\sqrt{73}}{12}
$


$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+\sqrt{73}}{2*6}=\frac{-7+\sqrt{73}}{12}
$
