(81x^2)-17x=70
We move all terms to the left:
(81x^2)-17x-(70)=0
a = 81; b = -17; c = -70;
Δ = b2-4ac
Δ = -172-4·81·(-70)
Δ = 22969
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{-(-17)-\sqrt{22969}}{2*81}=\frac{17-\sqrt{22969}}{162} $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-17)+\sqrt{22969}}{2*81}=\frac{17+\sqrt{22969}}{162} $
