Property of Square Roots You can simplify – any thing that appears twice can come out 50 32 You can split/combine multiplication and division 5×6 7 × 14 5 9 6 3

Property of Square Roots You cannot add/subtract different square roots 5 + 3 You can add/subtract same square roots 2 + 3 +5 3 You can rationalize the denominator by multiplying the top and bottom by the same number 5 3

Using Square Roots - 1 Solve 𝑥 2 =7 Solve 𝑥 2 =16 Solve 𝑥 2 =13

Using Square Roots - Inside 𝑥+1 2 =9 2𝑥−1 2 =25 𝑥+5 2 =4 𝟑𝒙−𝟏 𝟐 =𝟏𝟔

Using Square Roots - Both 𝑥−1 2 +1=5 3 2𝑥+3 2 =12 𝑥−1 2 +5=4 2 𝒙−𝟏 𝟐 =𝟏𝟐

Using Square Roots – Book Examples 3 𝑥 2 +9=0 2 5 𝑥+3 2 =5
