(2x-5)(3x+10)=0
We multiply parentheses ..
(+6x^2+20x-15x-50)=0
We get rid of parentheses
6x^2+20x-15x-50=0
We add all the numbers together, and all the variables
6x^2+5x-50=0
a = 6; b = 5; c = -50;
Δ = b2-4ac
Δ = 52-4·6·(-50)
Δ = 1225
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{1225}=35$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-35}{2*6}=\frac{-40}{12} =-3+1/3 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+35}{2*6}=\frac{30}{12} =2+1/2 $
