7u^2-55u-8=0
a = 7; b = -55; c = -8;
Δ = b2-4ac
Δ = -552-4·7·(-8)
Δ = 3249
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{3249}=57$$u_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-55)-57}{2*7}=\frac{-2}{14} =-1/7 $$u_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-55)+57}{2*7}=\frac{112}{14} =8 $
