Solution for x^2+6x=94 equation:



x^2+6x=94
We move all terms to the left:
x^2+6x-(94)=0
a = 1; b = 6; c = -94;
Δ = b2-4ac
Δ = 62-4·1·(-94)
Δ = 412
The delta value is higher than zero, so the equation has two solutions
We use following formulas to calculate our solutions:
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}$

The end solution:
$\sqrt{\Delta}=\sqrt{412}=\sqrt{4*103}=\sqrt{4}*\sqrt{103}=2\sqrt{103}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(6)-2\sqrt{103}}{2*1}=\frac{-6-2\sqrt{103}}{2} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(6)+2\sqrt{103}}{2*1}=\frac{-6+2\sqrt{103}}{2} $
