  • 7. Sadly, we have reached the end, the last warm-up question of the year..........
  • 8. 5x  1  3x 5  2. Set up the equation so that there will be only one radical on each side of the equal sign. Square both sides of the equation. Simplify. Simplify by dividing by a common factor of 2. Square both sides of the equation. 5x 1 2  2  3x  5 2 5x 1 5x 1 3x 1 4 3x  5 2x  2  4 3x  5 x 1 2 3x  5 x 1 2  2 3x  5 2 x2  2x 1  4(3x  5) Use Foil. 5x 1  2 3x  5 Use Foil. 4  4 3x  5  (3x  5) Solve Solving Radical Equations
