[SOLVED] √x-3 + √x = 3 more simple algebra
√x-3 + √x = 3
( √x-3 + √x ) ( √x-3 + √x ) = 9
I have the answer in my book as x=4 , but I don't understand how they got there.
these are the next two steps which I don't understand, everything after I get so I didn't type it here.
(x-3) + 2√x-3 √x + x = 9
2x - 3 + 2√x²-3x = 9 * the -3x is in the square root
