5x*3x+2*3x-6*3x-2=0
Wy multiply elements
15x^2+6x-18x-2=0
We add all the numbers together, and all the variables
15x^2-12x-2=0
a = 15; b = -12; c = -2;
Δ = b2-4ac
Δ = -122-4·15·(-2)
Δ = 264
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:
$\sqrt{\Delta}=\sqrt{264}=\sqrt{4*66}=\sqrt{4}*\sqrt{66}=2\sqrt{66}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-12)-2\sqrt{66}}{2*15}=\frac{12-2\sqrt{66}}{30} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-12)+2\sqrt{66}}{2*15}=\frac{12+2\sqrt{66}}{30} $
