-20x^2=25x-22
We move all terms to the left:
-20x^2-(25x-22)=0
We get rid of parentheses
-20x^2-25x+22=0
a = -20; b = -25; c = +22;
Δ = b2-4ac
Δ = -252-4·(-20)·22
Δ = 2385
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$
The end solution:
$\sqrt{\Delta}=\sqrt{2385}=\sqrt{9*265}=\sqrt{9}*\sqrt{265}=3\sqrt{265}$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-25)-3\sqrt{265}}{2*-20}=\frac{25-3\sqrt{265}}{-40} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-25)+3\sqrt{265}}{2*-20}=\frac{25+3\sqrt{265}}{-40} $
