Reformatting the input :
Changes made to your input should not affect the solution:
(1): "s0" was replaced by "s^0".
(2): Dot was discarded near "1.j".
Step 1 :
Trying to factor as a Difference of Squares:
1.1 Factoring: es2-jpg
Theory : A difference of two perfect squares, A2-B2can be factored into (A+B)•(A-B)Proof:(A+B)•(A-B)=
A2 - AB+BA-B2=
A2 -AB+ AB - B2 =
A2 - B2Note : AB = BA is the commutative property of multiplication.
Note : -AB+ AB equals zero and is therefore eliminated from the expression.
Check: e1 is not a square !!
Ruling : Binomial can not be factored as the difference of two perfect squares
Final result :
