(x+30)(5x-25)=4x
We move all terms to the left:
(x+30)(5x-25)-(4x)=0
We add all the numbers together, and all the variables
-4x+(x+30)(5x-25)=0
We multiply parentheses ..
(+5x^2-25x+150x-750)-4x=0
We get rid of parentheses
5x^2-25x+150x-4x-750=0
We add all the numbers together, and all the variables
5x^2+121x-750=0
a = 5; b = 121; c = -750;
Δ = b2-4ac
Δ = 1212-4·5·(-750)
Δ = 29641
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(121)-\sqrt{29641}}{2*5}=\frac{-121-\sqrt{29641}}{10} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(121)+\sqrt{29641}}{2*5}=\frac{-121+\sqrt{29641}}{10} $
