IMPORTANT NOTE: the "*" sign in the equations means it is the end point of the square root sign.
Solve the following equations:
1) Solve for x: √12* (√3* - x) = 15
2) Solve for x: √3x - 1* = 7 What is the root? If there is no root, choose none.
3) Solve for x: √3x* + 1 = 7 What is the root? If there is no root, choose none.
4) Solve for x: 3√x* + 1 = 7 What is the root? If there is no root, choose none.
5) Solve for x: √2y - 5* + 4 = 8 What is the root? If there is no root, choose none.
6) Solve for z: √z^2 + 5* - 2 = z What is the root? If there is no root, choose none.
