(2x+10)(2x+25)=936
We move all terms to the left:
(2x+10)(2x+25)-(936)=0
We multiply parentheses ..
(+4x^2+50x+20x+250)-936=0
We get rid of parentheses
4x^2+50x+20x+250-936=0
We add all the numbers together, and all the variables
4x^2+70x-686=0
a = 4; b = 70; c = -686;
Δ = b2-4ac
Δ = 702-4·4·(-686)
Δ = 15876
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{15876}=126$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(70)-126}{2*4}=\frac{-196}{8} =-24+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(70)+126}{2*4}=\frac{56}{8} =7 $
