22.500+100x+0.01x^2=0
We add all the numbers together, and all the variables
0.01x^2+100x+22.5=0
a = 0.01; b = 100; c = +22.5;
Δ = b2-4ac
Δ = 1002-4·0.01·22.5
Δ = 9999.1
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{-(100)-\sqrt{9999.1}}{2*0.01}=\frac{-100-\sqrt{9999.1}}{0.02} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(100)+\sqrt{9999.1}}{2*0.01}=\frac{-100+\sqrt{9999.1}}{0.02} $
