(2x+10)(3x-6)=0
We multiply parentheses ..
(+6x^2-12x+30x-60)=0
We get rid of parentheses
6x^2-12x+30x-60=0
We add all the numbers together, and all the variables
6x^2+18x-60=0
a = 6; b = 18; c = -60;
Δ = b2-4ac
Δ = 182-4·6·(-60)
Δ = 1764
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{1764}=42$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(18)-42}{2*6}=\frac{-60}{12} =-5 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(18)+42}{2*6}=\frac{24}{12} =2 $
