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
