4x^2-178x+420=0
a = 4; b = -178; c = +420;
Δ = b2-4ac
Δ = -1782-4·4·420
Δ = 24964
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}$$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$$\sqrt{\Delta}=\sqrt{24964}=158$$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(-178)-158}{2*4}=\frac{20}{8} =2+1/2 $$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-178)+158}{2*4}=\frac{336}{8} =42 $
