0=-19.21x^2+88.76x
We move all terms to the left:
0-(-19.21x^2+88.76x)=0
We add all the numbers together, and all the variables
-(-19.21x^2+88.76x)=0
We get rid of parentheses
19.21x^2-88.76x=0
a = 19.21; b = -88.76; c = 0;
Δ = b2-4ac
Δ = -88.762-4·19.21·0
Δ = 7878.3376
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{-(-88.76)-\sqrt{7878.3376}}{2*19.21}=\frac{88.76-\sqrt{7878.3376}}{38.42} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-88.76)+\sqrt{7878.3376}}{2*19.21}=\frac{88.76+\sqrt{7878.3376}}{38.42} $
