7n^2-68n=0
a = 7; b = -68; c = 0;
Δ = b2-4ac
Δ = -682-4·7·0
Δ = 4624
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{4624}=68$$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-68)-68}{2*7}=\frac{0}{14} =0 $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-68)+68}{2*7}=\frac{136}{14} =9+5/7 $
