Solution for x2-1X=35 equation:

x2-1x=35

We move all terms to the left:

x2-1x-(35)=0

We add all the numbers together, and all the variables

x^2-1x-35=0

a = 1; b = -1; c = -35;
Δ = b2-4ac
Δ = -12-4·1·(-35)
Δ = 141
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{141}}{2*1}=\frac{1-\sqrt{141}}{2}
$
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(-1)+\sqrt{141}}{2*1}=\frac{1+\sqrt{141}}{2}
