x=2 is the only solution

Step-by-step explanation:

The given expression is;

Split the middle term

x=-3,or x=2

Check for extraneous solutions by substituting into the original equation.

When x=-3,

This is an extraneous solution.

When x=2,

. This is true

This is not an extraneous solution

its the fourth option
