(5x+2)(2x-3)=0
We multiply parentheses ..
(+10x^2-15x+4x-6)=0
We get rid of parentheses
10x^2-15x+4x-6=0
We add all the numbers together, and all the variables
10x^2-11x-6=0
a = 10; b = -11; c = -6;
Δ = b2-4ac
Δ = -112-4·10·(-6)
Δ = 361
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{361}=19$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-11)-19}{2*10}=\frac{-8}{20} =-2/5 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+19}{2*10}=\frac{30}{20} =1+1/2 $
