5(4x+3)x-7)=0
We add all the numbers together, and all the variables
5(4x+3)x=0
We multiply parentheses
20x^2+15x=0
a = 20; b = 15; c = 0;
Δ = b2-4ac
Δ = 152-4·20·0
Δ = 225
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{225}=15$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(15)-15}{2*20}=\frac{-30}{40} =-3/4 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(15)+15}{2*20}=\frac{0}{40} =0 $
