4x^2+0.26x-1.248=0
a = 4; b = 0.26; c = -1.248;
Δ = b2-4ac
Δ = 0.262-4·4·(-1.248)
Δ = 20.0356
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{-(0.26)-\sqrt{20.0356}}{2*4}=\frac{-0.26-\sqrt{20.0356}}{8} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0.26)+\sqrt{20.0356}}{2*4}=\frac{-0.26+\sqrt{20.0356}}{8} $
