 x =(14-√28)/2=7-√ 7 = 4.354

 x =(14+√28)/2=7+√ 7 = 9.646

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "x2"   was replaced by   "x^2". 

Step by step solution :

Step  1  : Raise  x to the  2nd power

Exponentiaion : Equation at the end of step  1  :

  (x2 -  14x) +  42  = 0 

Step  2  :

Simplify   x2-14x  +  42

Thanks
