5x(2x+20)=180
We move all terms to the left:
5x(2x+20)-(180)=0
We multiply parentheses
10x^2+100x-180=0
a = 10; b = 100; c = -180;
Δ = b2-4ac
Δ = 1002-4·10·(-180)
Δ = 17200
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{17200}=\sqrt{400*43}=\sqrt{400}*\sqrt{43}=20\sqrt{43}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(100)-20\sqrt{43}}{2*10}=\frac{-100-20\sqrt{43}}{20} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(100)+20\sqrt{43}}{2*10}=\frac{-100+20\sqrt{43}}{20} $
