Chapter 3

1. Quadratic formulas

1.1. If ax^2+bx+c=0

1.2. Roots are -b+or-\sqrt{b^2}-4ac

2. Degree of a Polynomial

2.1. highest degree of its monomials

3. Coefficient

3.1. A numerical or constant quantity placed before and multiplying the variable in an algebraic expression

4. Like Terms

4.1. Contain the same variables raised to the same power.

5. Root of an equation

5.1. Real number (x)

5.2. Exactly the x-intercepts of the quadratic function

5.3. Finding the roots of a quadratic equation with the quadratic formula is easy - just use plug a, b, and c into the formula and solve for x!

6. Standard Form

6.1. moving the x-term to the left side of the equation. This is done by subtracting mx from both sides.

7. Polynomial

7.1. an expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variable(s).
