(X-2)(y+2)=360

Solution for (X-2)(y+2)=360 equation:

(X-2)(X+2)=360

We move all terms to the left:

(X-2)(X+2)-(360)=0

We use the square of the difference formula

X^2-4-360=0

We add all the numbers together, and all the variables

X^2-364=0

a = 1; b = 0; c = -364;
Δ = b2-4ac
Δ = 02-4·1·(-364)
Δ = 1456
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:

$\sqrt{\Delta}=\sqrt{1456}=\sqrt{16*91}=\sqrt{16}*\sqrt{91}=4\sqrt{91}$
$X_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{91}}{2*1}=\frac{0-4\sqrt{91}}{2}
=-\frac{4\sqrt{91}}{2}
=-2\sqrt{91}
$
$X_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{91}}{2*1}=\frac{0+4\sqrt{91}}{2}
=\frac{4\sqrt{91}}{2}
=2\sqrt{91}
