2w^2-13w+11=0
a = 2; b = -13; c = +11;
Δ = b2-4ac
Δ = -132-4·2·11
Δ = 81
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{81}=9$$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-13)-9}{2*2}=\frac{4}{4} =1 $$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-13)+9}{2*2}=\frac{22}{4} =5+1/2 $
