What distinguishes a quadratic equation from a linear equation?

• It has a constant term.

• It includes an x^2 term.

• It is always equal to zero.

• It has no variable terms.

In the square root method, what must you remember when taking the square root of both sides?

• Only consider the negative root.

• Only consider the positive root.

• Ignore the negative root.

• Consider both positive and negative roots.

What is the purpose of factoring a quadratic equation?

• To eliminate the x^2 term.

• To find the roots using the zero product property.

• To simplify the equation.

• To convert it into a linear equation.

When completing the square, what is the first step?

• Add the middle term to both sides.

• Divide the middle term by two and square it.

• Subtract the middle term from both sides.

• Multiply the middle term by two.

What is the quadratic formula used for?
