Slide 6 - Slide

Equations with square roots

Solve.

Slide 7 - Slide

Solve:

\sqrt ​ x ​ ​ ​ = 25

x = \sqrt ​ 5 ​ ​ ​

x = 25

x = 625

Cannot be solved

Slide 8 - Quiz

Solve:

\sqrt ​ x - 1 ​ ​ ​ = 5

x = 25

x = 26

x = 6

Cannot be solved

Slide 9 - Quiz

Solve:

- \sqrt ​ x + 4 ​ ​ ​ = - 2

x = 4

x = - 2

x = 0

Cannot be solved
