Solution for 6x2-4x=5 equation:



6x^2-4x=5
We move all terms to the left:
6x^2-4x-(5)=0
a = 6; b = -4; c = -5;
Δ = b2-4ac
Δ = -42-4·6·(-5)
Δ = 136
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{136}=\sqrt{4*34}=\sqrt{4}*\sqrt{34}=2\sqrt{34}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-4)-2\sqrt{34}}{2*6}=\frac{4-2\sqrt{34}}{12} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-4)+2\sqrt{34}}{2*6}=\frac{4+2\sqrt{34}}{12} $
