2x^2-3x-69=0
a = 2; b = -3; c = -69;
Δ = b2-4ac
Δ = -32-4·2·(-69)
Δ = 561
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{-(-3)-\sqrt{561}}{2*2}=\frac{3-\sqrt{561}}{4} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-3)+\sqrt{561}}{2*2}=\frac{3+\sqrt{561}}{4} $
