x^2+10x+22.5=0
a = 1; b = 10; c = +22.5;
Δ = b2-4ac
Δ = 102-4·1·22.5
Δ = 10
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{-(10)-\sqrt{10}}{2*1}=\frac{-10-\sqrt{10}}{2} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(10)+\sqrt{10}}{2*1}=\frac{-10+\sqrt{10}}{2} $
