4x² + 4x - 3 = 0
         + 4   4   <--- add 4 to both sides.
----------------
4x² + 4x + 1 = 4
(2x+1)(2x+1) = 4
     (2x+1)² = 4
        2x+1 = ±√4
        2x+1 = ±2

Using the +

        2x+1 = 2
          2x = 1
           x = 1%2F2 
    
Using the -

        2x+1 = -2
          2x = -3
           x = -3%2F2
