Solve the radical equation. What is the extraneous solution to the radical equation?

Both 1 and 9 are extraneous solutions to the equation.

There are no extraneous solutions to the equation.

What is the solution to the equation 4 + = 6?

y = 1

y = 4

y = 500

y = 2000

Solve the radical equation. = n – 3

There are no extraneous solutions to the equation.

Which equation is equivalent to = 36?

= 3

x + 15 = 9

x + 15 = –6

= 24

Jacob is solving the equation = 27 for q. His work is shown. = 27 = 9 = 923q = A q = B

A = 3B = 1

A = 9B = 3

A = 18B = 6

A = 81B = 27

Sebastian solved the radical equation y + 1 = but did not check his solution.(y + 1)2 = y2 + 2y + 1 = –2y – 3y2 + 4y + 4 = 0(y + 2)(y + 2) = 0y = –2

y = –2

y = 1

y = 2

There are no true solutions to the equation.

Narine is solving the equation = 6 for q. Her work is shown. = 6 = 623q = Aq = B

A = 6 B = 2

A = 9 B = 3

A = 12 B = 4

A = 36 B = 12

Solve the radical equation. = x – 10

–15

–5

There are no true solutions.

Both –5 and –15 and are true solutions.

Consider the radical equation = n – 2. Which statement is true about the solutions n = 5 and n = 0?

The solution n = 5 is an extraneous solution.

Both n = 5 and n = 0 are true solutions.
