(2x-5)(4x/3+7)=0
We multiply parentheses ..
(+8x^2+14x-20x-35)=0
We get rid of parentheses
8x^2+14x-20x-35=0
We add all the numbers together, and all the variables
8x^2-6x-35=0
a = 8; b = -6; c = -35;
Δ = b2-4ac
Δ = -62-4·8·(-35)
Δ = 1156
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{1156}=34$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-6)-34}{2*8}=\frac{-28}{16} =-1+3/4 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-6)+34}{2*8}=\frac{40}{16} =2+1/2 $
