2. Solve x for each equation. Check for extraneous roots when necessary. a) 9-3*-8=0 b) 25(125)*+2, = 625 1-x c) Log (x-1) + log (2x -1) = 2log (x + 1)

9. Solve each question below – show all steps for full marks and reject all extraneous roots! a. 4x-2 + 4x-1 = 20 b. -8log2(x-1) = -32 c. log4(x-3) + log4(x+3) = 2
