(7x-15)(5x-19)=0
We multiply parentheses ..
(+35x^2-133x-75x+285)=0
We get rid of parentheses
35x^2-133x-75x+285=0
We add all the numbers together, and all the variables
35x^2-208x+285=0
a = 35; b = -208; c = +285;
Δ = b2-4ac
Δ = -2082-4·35·285
Δ = 3364
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{3364}=58$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-208)-58}{2*35}=\frac{150}{70} =2+1/7 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-208)+58}{2*35}=\frac{266}{70} =3+4/5 $
