1.8x^2-8.4x+5.6=0
a = 1.8; b = -8.4; c = +5.6;
Δ = b2-4ac
Δ = -8.42-4·1.8·5.6
Δ = 30.24
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{-(-8.4)-\sqrt{30.24}}{2*1.8}=\frac{8.4-\sqrt{30.24}}{3.6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-8.4)+\sqrt{30.24}}{2*1.8}=\frac{8.4+\sqrt{30.24}}{3.6} $
