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  :

Equation at the end of step  1  :

 ((x2)+(2x•(y+z)))+2•(y+z)

Step  2  :

Equation at the end of step  2  :

 ((x2)+2x•(y+z))+2•(y+z)

Step  3  :

Final result :

 x2 + 2xy + 2xz + 2y + 2z
