(7x+5)(x-6)=0
We multiply parentheses ..
(+7x^2-42x+5x-30)=0
We get rid of parentheses
7x^2-42x+5x-30=0
We add all the numbers together, and all the variables
7x^2-37x-30=0
a = 7; b = -37; c = -30;
Δ = b2-4ac
Δ = -372-4·7·(-30)
Δ = 2209
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{2209}=47x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-37)-47}{2*7}=\frac{-10}{14} =-5/7x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-37)+47}{2*7}=\frac{84}{14} =6
