w^2+6w=174

Solution for w^2+6w=174 equation:

w^2+6w=174

We move all terms to the left:

w^2+6w-(174)=0

a = 1; b = 6; c = -174;
Δ = b2-4ac
Δ = 62-4·1·(-174)
Δ = 732
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:

$\sqrt{\Delta}=\sqrt{732}=\sqrt{4*183}=\sqrt{4}*\sqrt{183}=2\sqrt{183}$
$w_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-2\sqrt{183}}{2*1}=\frac{-6-2\sqrt{183}}{2}
$
$w_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+2\sqrt{183}}{2*1}=\frac{-6+2\sqrt{183}}{2}
