Explanation The given equation is 3 x − 2 − x + 7 = 1 . Isolate the radical by adding x + 7 from both sides of the equation as follows. 3 x − 2 − x + 7 + x + 7 = 1 + x + 7 3 x − 2 = 1 + x + 7 Take square on both sides and simplify as follows. ( 3 x − 2 ) 2 = ( 1 + x + 7 ) 2 3 x − 2 = 1 + x + 7 + 2 x + 7 3 x − 2 − 8 − x = 2 x + 7 2 x − 10 = 2 x + 7 Take square on both sides and simplify as follows. ( 2 x − 10 ) 2 = ( 2 x + 7 ) 2 4 x 2 + 100 − 40 x = 4 ( x + 7 ) 4 x 2 + 100 − 40 x = 4 x + 28 4 x 2 − 44 x + 72 = 0 On further simplification, x 2 − 11 x + 18 = 0 (
