Standard Form

ax2 + bx + c = 0

Factoring and Solving

- Rule 1 (the only rule)
- Find the G.C.F.
- Otherwise, look for something familiar

If factoring does not seem to be working…..

- Ask the following question:
- “Is the linear term missing?”
- If so, SQUARE ROOTS SEEM GOOD.

Square Root Method

- If you take the square root of both sides of an equation, then you must get TWO answers.

Don't forget

the

PERFECT SQUARED TRINOMIALS

- “FIRST TERM SQUARED PLUS TWICE THE FIRST TIMES THE LAST PLUS THE LAST TERM SQUARED.”
- Can be factored from a memorized formula.

Differences of Squares

- A difference of two squares can be factored.
- Remember that the inner and outer terms must be opposites.

A manufacturer determines that the number of drills it can sell is given by the formula where p is the price of the drills in dollars.

- At what price will the manufacturer sell the
- maximum number of drills?
- b. What is the maximum number of drills that can be sold?

Factor the expression. sell is given by the formula where p is the price of the drills in dollars.

or sell is given by the formula where p is the price of the drills in dollars.

Solve by factoring.Solve the equation by sell is given by the formula where p is the price of the drills in dollars. finding square roots

Solve the equation. sell is given by the formula where p is the price of the drills in dollars.

Solve the equation. sell is given by the formula where p is the price of the drills in dollars.

Solve by completing the square. sell is given by the formula where p is the price of the drills in dollars.

Solve by completing the square. sell is given by the formula where p is the price of the drills in dollars.

Rewrite in Vertex Form sell is given by the formula where p is the price of the drills in dollars.
