Order the following steps for solving quadratic equations by factoring.

Set the quadratic equation equal to zero.

Set each factor equal to zero, and solve each for the variable.

Reorder the following steps to solve a quadratic equation when the leading coefficient is not 1 ( a > 1 ) to solve the equation by completing the square .

Divide the entire equation by a

Reorder the following steps to solve a quadratic equation by using the quadratic formula .

Make sure the equation is set equal to 0 and written in standard form . a x 2 + b x + c = 0

Substitute these values into the formula

Simplify using the order of operations (PEMDAS)

When is a quadratic equation factorable ?

When the discriminant (d=b 2 −4ac) is a perfect square

When the diagonal (ax=y) is a perfect square

When the difference (d=ax 2 −c) is a perfect square

When the difference (d=ax 2 −c) is a perfect cube

When the discriminant (d=b 2 −4ac) is a perfect cube

What are the steps to solving this by completing the square?
x² + 10x + 21 = 0

Subtract 5 from both sides of the equation

Subtract 21 from both sides of the equation

Add 25 to both sides of the equation

Rewrite the left hand side as a (binomial)²

Take the square root of both sides of the equation

Answer explanation

Steps for completing the square when a=1
1st: Rewrite as x² + bx = c
2nd: Take half of b, square it, then add this to both sides.
3rd: Factor the perfect square trinomial.
4th: Take the square root of both sides and solve for both cases.
5th: Write the answer using curly braces in set notation
