Introduction to Factoring Quadratic Trinomials
A quadratic trinomial is a polynomial with three terms. In two of the terms the same variable appears, one that is raised to the second power and the other with an exponent of one. The third term in a quadratic trinomial is a constant. To factor a q...
Not All Quadratic Trinomials Can Be Factored
A quadratic trinomial that cannot be factored is presented and explained.
Factor: d2 - 13d 30
The terms in a quadratic trinomial can be positive or negative. A quadratic trinomial in which the middle term is negative is factored.
Writing a Slope-intercept Equation from a Graph
Constructing a slope-intercept form of equation based on a graph.
Multiplying Signed Numbers: Summary: Multiplying Signed Numbers
This clip reviews the basic rules that apply to multiplying signed numbers. If the two signs are the same, the answer is positive. If they're different, the answer is negative. And, when multiplying more than two signed numbers, if there's an even n...
Finding Rate of Change From a Graphed Line
The procedure for finding rate of change from a graphed line is detailed.
Factoring Perfect Square Trinomials
The perfect square trinomial is a polynomial that can be factored using a special formula. In standard form, the first and last terms of a perfect square trinomial are always perfect squares. The middle term is always the product of the square roots...
