(5x-5)(2x+3)=0
We multiply parentheses ..
(+10x^2+15x-10x-15)=0
We get rid of parentheses
10x^2+15x-10x-15=0
We add all the numbers together, and all the variables
10x^2+5x-15=0
a = 10; b = 5; c = -15;
Δ = b2-4ac
Δ = 52-4·10·(-15)
Δ = 625
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{625}=25$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(5)-25}{2*10}=\frac{-30}{20} =-1+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(5)+25}{2*10}=\frac{20}{20} =1 $
