3x(x-12)+5(x-2)=0
We multiply parentheses
3x^2-36x+5x-10=0
We add all the numbers together, and all the variables
3x^2-31x-10=0
a = 3; b = -31; c = -10;
Δ = b2-4ac
Δ = -312-4·3·(-10)
Δ = 1081
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{-(-31)-\sqrt{1081}}{2*3}=\frac{31-\sqrt{1081}}{6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-31)+\sqrt{1081}}{2*3}=\frac{31+\sqrt{1081}}{6} $
