13.8x^2+2x-0.26=0
a = 13.8; b = 2; c = -0.26;
Δ = b2-4ac
Δ = 22-4·13.8·(-0.26)
Δ = 18.352
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{-(2)-\sqrt{18.352}}{2*13.8}=\frac{-2-\sqrt{18.352}}{27.6} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(2)+\sqrt{18.352}}{2*13.8}=\frac{-2+\sqrt{18.352}}{27.6} $
