Read each question carefully and solve for the variable. Remember to check for extraneous solutions.

1. Solve the equation: √(3x + 4) = 5

2. Find the solution(s) for: √(x - 1) + 3 = x

3. When solving radical equations, it is crucial to check for solutions, which are values that satisfy a transformed equation but not the original one.

4. The equation √(x + 2) = x - 4 has an extraneous solution of x = .

5. Solve for y: ∛(2y - 7) = 3

6. Determine the value of z in the equation: ∛(z^2 + 1) = 2

7. Which of the following is an extraneous solution to √(x + 6) = x?

x = -2

x = 3

x = -3

No extraneous solutions

8. The equation √(x - 5) = -2 has no real solutions.

True

False
