4n^2-3n-870=0
a = 4; b = -3; c = -870;
Δ = b2-4ac
Δ = -32-4·4·(-870)
Δ = 13929
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}$$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$n_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-3)-\sqrt{13929}}{2*4}=\frac{3-\sqrt{13929}}{8} $$n_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-3)+\sqrt{13929}}{2*4}=\frac{3+\sqrt{13929}}{8} $
