3.2x^2+-8.5x+1.3=0
We add all the numbers together, and all the variables
3.2x^2-8.5x=0
a = 3.2; b = -8.5; c = 0;
Δ = b2-4ac
Δ = -8.52-4·3.2·0
Δ = 72.25
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{-(-8.5)-\sqrt{72.25}}{2*3.2}=\frac{8.5-\sqrt{72.25}}{6.4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-8.5)+\sqrt{72.25}}{2*3.2}=\frac{8.5+\sqrt{72.25}}{6.4} $
