Ineed with my algebra 2. i also want to know how to solve this.

Add 1 to both sides:

In cases like this, we have to remember that a root is always positive, so we can square both sides only assuming that

Under this assumption, we square both sides and we have

The solutions to this equation are

But since we can only accept solutions greater than -1, we discard and accept .

In fact, we have

and

which is the only solution.

just get this app called photo math it should be able to do those

i have not got your picture clearly so see it once again
