_______ Ö8x - 17 - 1 = 0
_______ Ö8x - 17 - 1 = 0 Isolate the radical term _______ Ö8x - 17 = 1 Square both sides: _______ (Ö8x - 17)² = (1)² 8x - 17 = 1 8x = 18 x = 18/8 x = 9/4 We must check a radical equation because sometimes an answer we get does not check even though we did nothing wrong. _______ Ö8x - 17 - 1 = 0 ___________ Ö8(9/4) - 17 - 1 = 0 _______ Ö18 - 17 - 1 = 0 _ Ö1 - 1 = 0 1 - 1 = 0 0 = 0 So x = 9/4 checks and thus is the only solution.
