(x+25)(4x+10)=180
We move all terms to the left:
(x+25)(4x+10)-(180)=0
We multiply parentheses ..
(+4x^2+10x+100x+250)-180=0
We get rid of parentheses
4x^2+10x+100x+250-180=0
We add all the numbers together, and all the variables
4x^2+110x+70=0
a = 4; b = 110; c = +70;
Δ = b2-4ac
Δ = 1102-4·4·70
Δ = 10980
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{10980}=\sqrt{36*305}=\sqrt{36}*\sqrt{305}=6\sqrt{305}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(110)-6\sqrt{305}}{2*4}=\frac{-110-6\sqrt{305}}{8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(110)+6\sqrt{305}}{2*4}=\frac{-110+6\sqrt{305}}{8} $
