We add all the numbers together, and all the variables

X^2+7X-166=0

a = 1; b = 7; c = -166;
Δ = b2-4ac
Δ = 72-4·1·(-166)
Δ = 713
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{-(7)-\sqrt{713}}{2*1}=\frac{-7-\sqrt{713}}{2}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(7)+\sqrt{713}}{2*1}=\frac{-7+\sqrt{713}}{2}
