**10.4**Solving Quadratic Equations by the Square Root Method**Square Root Method**• Use if there is no linear term. (i.e. B = 0) • Get the Quadratic Term on one side and the Constant on the other side. • Simply take the Square Root of Both Sides.**Square Root Method**Be sure to give both the positive and negative answers!**Square Root Method**Be sure to give both the positive and negative answers!**Solve by using the Square Root Property.**Original equation Factor the perfect square trinomial. Square Root Property Subtract 7 from each side. Write as two equations. or Solve each equation. Example 4-1a Answer:The solution set is {–15, 1}.**Solve by using the Square Root Property.**Example 4-1b Answer:{3, 13}**Solve by using the Square Root Property.**Original equation Factor the perfect square trinomial. Square Root Property Add 5 to each side. Write as two equations. or Use a calculator. Example 4-2a**Example 4-6b**Classwork/Homework
