(2x-3)(7x+5)=0
We multiply parentheses ..
(+14x^2+10x-21x-15)=0
We get rid of parentheses
14x^2+10x-21x-15=0
We add all the numbers together, and all the variables
14x^2-11x-15=0
a = 14; b = -11; c = -15;
Δ = b2-4ac
Δ = -112-4·14·(-15)
Δ = 961
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{961}=31$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-11)-31}{2*14}=\frac{-20}{28} =-5/7 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-11)+31}{2*14}=\frac{42}{28} =1+1/2 $
