A2_6.7.1 Video Lesson - Solving Radical Equations

What is the first step when solving equations with radicals?

• Simplify the equation first.
• Add the exponents.
• Multiply both sides by a constant.
• Isolate the radical.

Why do we have to plug in our solution after solving?

• To find alternative solutions.
• To simplify the problem further.
• To change the original equation.
• To verify the solution isn't extraneous.

In the 3rd example, why can't we simplify the right side to "x-1"?

• The right side simplifies to 'x-2'.

• The right side simplifies to 'x+1'.
• The right side equals 'x-3' instead.
• The -1 is NOT inside the radical.

How do we decide what power to raise the radical to when solving?

• Divide the radical by its index.
• Subtract the index from the radical.
• Raise the radical to the power of its index (or root).

• Multiply the radical by its index.
