Hey everyone! I'm doing some self teaching in math with a book that only shows answers but not how you get to the answers. Please help me with this equation, I just can't figure it out:
√(4x+9) - 2 = √(3x-5) The answers are 10 and 18
I tried bringing the square roots on one side and squaring the whole thing but I come to -10, which is false. How does this work?
Thank you in advance,
Giovanni
