no I was mistake it goes away when you get rid of x and square both sides

ok, then divide both sides by 2. then square both sides. thank you!

could one of you give me a different problem that is still similar math?

k. thank you. give me a minute to do it, then could you let me know if i did it right?

It will come as a negative fraction, don't bother simplifying.

Its ok if the answer looks too complicated, I made up the question on the spot.

i thought when you divide a fraction by another fraction you are really just multiplying it by the reciprocal.

ohh..... never mind... I get it 1/2 is the reciprocal of 2... duh.

√(x+5)  1 = √x √x + 1 = √(x+5) by squaring both sides, (√x + 1)² = [√(x + 5)]² (√x)² + 2 * √x * 1 + 1² = x + 5 x + 2√x + 1 = x + 5 2√x = 5  1 √x = 4/2 x = 2² x = 4
