2-√(x+1)= √(x+3) 2-sqrt(x+1)=sqrt(x+3) [2-sqrt(x+1)]^2=[sqrt(x+3)]^2 4 - 4sqrt(x + 1) + x + 1 = x + 3 Isolate the square root 4 + x + 1 - x - 3 = 4sqrt(x + 1) 2 = 4sqrt(

Multiply both sides by 6(2x+1), 6(x+2) = 2x(2x+1) + 9. => 4x^2 - 4x - 3 = 0. => (2x+1)(2x-3) = 0. x = 3/2.------. Attn: x = -1/2 is not a solution because at x = -1/

1. Search the answers appendix at the back of the textbook. Notice that it contains at least half the answers, covering either all the odd numbered questions or the evens. Work backward
