Solve for a Variable with radical

What is the first step in solving an equation that includes a radical?

• Perform addition on both sides

• Isolate the radical on one side

• Square both sides immediately

• Substitute known values

After isolating the radical, what is the next mathematical operation performed?

• Squaring

• Multiplication

• Subtraction

• Addition

What is the result of squaring the isolated radical equation?

• 4 + W

• 4 - W

• W - 4

• W + 4

What should you always do after solving the equation?

• Start a new problem

• Multiply the result by -1

• Check your answer by substituting back into the original equation

• Ignore checking as it is always correct

What does substituting W = -12 into the original equation confirm?

• No solution exists

• The equation becomes undefined

• The solution W = -12 is correct

• The solution is incorrect
