7x^2-49x-1=0
a = 7; b = -49; c = -1;
Δ = b2-4ac
Δ = -492-4·7·(-1)
Δ = 2429
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{-(-49)-\sqrt{2429}}{2*7}=\frac{49-\sqrt{2429}}{14} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-49)+\sqrt{2429}}{2*7}=\frac{49+\sqrt{2429}}{14} $
