What is the first step in solving a quadratic equation using square roots?

• Subtract a constant from both sides

• Multiply both sides by a number

• Add a constant to both sides

• Isolate the X squared term

When solving X squared equals 16, what are the possible values of X?

• 4 and -4

• Only -4

• Only 4

• Neither 4 nor -4

What should you do if you encounter a negative number under the square root?

• Add a positive number to make it positive

• Take the square root as usual

• Ignore it

• Recognize it as not a real number

In vertex form, what must be isolated to solve for X?

• The entire equation

• The X minus H term

• The constant term

• The coefficient of X

Why can't you add a whole number to a square root in the final answer?

• It changes the value of X

• It is not allowed in math

• They are unlike terms

• It makes the equation incorrect
