x^2-x-88.1002=0

Solution for x^2-x-88.1002=0 equation:

x^2-x-88.1002=0

We add all the numbers together, and all the variables

x^2-1x-88.1002=0

a = 1; b = -1; c = -88.1002;
Δ = b2-4ac
Δ = -12-4·1·(-88.1002)
Δ = 353.4008
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{-(-1)-\sqrt{353.4008}}{2*1}=\frac{1-\sqrt{353.4008}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+\sqrt{353.4008}}{2*1}=\frac{1+\sqrt{353.4008}}{2}
