Solution for (2x-1)*(2x+1)=37 equation:



(2x-1)(2x+1)=37
We move all terms to the left:
(2x-1)(2x+1)-(37)=0
We use the square of the difference formula
4x^2-1-37=0
We add all the numbers together, and all the variables
4x^2-38=0
a = 4; b = 0; c = -38;
Δ = b2-4ac
Δ = 02-4·4·(-38)
Δ = 608
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:
$\sqrt{\Delta}=\sqrt{608}=\sqrt{16*38}=\sqrt{16}*\sqrt{38}=4\sqrt{38}$
$x_{1}=\frac{-b-\sqrt{\Delta}}{2a}=\frac{-(0)-4\sqrt{38}}{2*4}=\frac{0-4\sqrt{38}}{8} =-\frac{4\sqrt{38}}{8} =-\frac{\sqrt{38}}{2} $
$x_{2}=\frac{-b+\sqrt{\Delta}}{2a}=\frac{-(0)+4\sqrt{38}}{2*4}=\frac{0+4\sqrt{38}}{8} =\frac{4\sqrt{38}}{8} =\frac{\sqrt{38}}{2} $
