Completing the Square Quiz

What do all quadratic equations discussed in the introduction have in common?

• They are all linear equations.

• They are all perfect square trinomials.

• They all have imaginary solutions.

• They are all cubic equations.

What is the first step in completing the square for a quadratic expression?

• Take the square root of the constant term.

• Subtract the constant term from both sides.

• Identify the coefficient of the linear term.

• Multiply the entire equation by 2.

When completing the square, what do you do after finding b/2 and squaring it?

• Divide the entire equation by it.

• Subtract it from the constant term.

• Add it to both sides of the equation.

• Multiply it by the coefficient of x.

How do you solve a quadratic equation after completing the square?

• Factor the equation completely.

• Use the quadratic formula.

• Take the square root of both sides.

• Graph the equation and find the intercepts.

What must be done to maintain balance when adding a term to complete the square?

• Add the term to only one side.

• Multiply the term by the coefficient of x.

• Subtract the term from both sides.

• Add the term to both sides.

In advanced techniques, what is a common method to handle fractions?

• Convert them to decimals.

• Ignore them and proceed with integers.

• Multiply the entire equation by the denominator.

• Leave them as fractions for easier squaring.

What is the purpose of rationalizing the denominator in a solution?

• To convert the solution to a fraction.

• To eliminate the square root.

• To make the solution more complex.

• To simplify the expression.

What indicates that a quadratic equation has no solution when completing the square?

• The equation has a positive constant term.

• The equation results in a negative number under a square root.

• The equation has a large constant term.

• The equation has a zero coefficient for x.

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

• Convert it to a positive number.

• Recognize that there is no real solution.

• Ignore the negative sign.

• Continue solving as usual.
