Step 2:

By addition property of equality, add
on both side of the equation.

Step 3:

Step 4:
Multiply by
on both side of the equation.

Hence Rahul use addition property of equality in step 2.
For all exponents, (a^n a^m) = a^(n+m)
apply same rules (X^3X^2)/(4*3)
Combine powers. (X^3X^2)/4*3 = X^(3+2)/4*3
X^5/12
