Answer 2

 4.3     Solving    x2-4x+4 = 0 by the Quadratic Formula .

 According to the Quadratic Formula,  x  , the solution for   Ax2+Bx+C  = 0  , where  A, B  and  C  are numbers, often called coefficients, is given by :
                                     
            - B  ±  √ B2-4AC
  x =   ————————
                      2A 

  In our case,  A   =     1
                      B   =    -4
                      C   =   4 

Accordingly,  B2  -  4AC   =
                     16 - 16 =
                     0

Applying the quadratic formula :

               4 ± √ 0 
   x  =    ————
                   2

The square root of zero is zero 

This quadratic equation has one solution only. That's because adding zero is the same as subtracting zero.

The solution is:
  x = 4 / 2 = 2
