To add the variables, add the coefficients with same variable. The expression which is equivalent to given expression is
. The option 2 is the correct option.
<h3>What is
equivalent expression?</h3>
Equivalent expression are the expression whose result is equal to the original expression, but the way of representation is different.
Given information-
The expression given in the problem is,

Let the resultant expression of the above expression is
. thus,

To add the algebraic terms open the brackets first,

Separate the same variable terms,

To add the variables, add the coefficients with same variable. Thus,

Hence, the expression which is equivalent to given expression is
. The option 2 is the correct option.
