Quadratics are also called second degree polynomials because the highest exponent is 2. Why study quadratics? The graphs of quadratic equations result in parabolas U shaped graphs that open up or down.

Subtract from both sides of the equation. Divide each term in by and simplify. Divide each term in by. Simplify the left side. Dividing two negative values results in a positive value. Divide by. Simplify the right side. Simplify each term. Step 1.

Explanation : The point 0, 0 is both the time and height intercept. Graph the equation Plot the points: Vertex.

.

Just for a moment let is pretend that the coefficient was negative. Find the mid point and that is the x coordinate for the minimum. Substitute back into the equation to determine the y coordinate. The y can be read off directly but you need to multiply the x equivalent by The inclusion of k neutralises that error. It is much less work. You can not factorise. Thus the graph can not cross the x-axis.

Divide by. This section shows us how to solve a new type of equation, the quadratic. The A intercept is 0, 0. This section explores further key points in the graph of a quadratic, the vertex and the intercepts. Substitute the value of into the formula. During the course of an experiment, the temperature of oxygen must be monitored. FOIL is a simple mnemonic to remember how to multiply two binomials. The rock is on the ground at zero seconds, before it is shot, which is the Height Intercept and at 4 seconds, when it returns to the ground. Use the properties of the parabola to analyze and graph the parabola. One to any power is one.

Since the value of is positive, the parabola opens up. Find the P intercept. Partial Fractions. Go Back: This is the same model that was used in Example 3 on page Suppose the total area has to be square meters. Why study quadratics? Find the distance from the vertex to a focus of the parabola by using the following formula. You can only compute the square root of nonnegative numbers. Write your answers in your homework notebook or make a copy of the test. If the area of the two pens must total 20, square yards, what should the dimensions of the pens be? Substitute the known values of and into the formula and simplify. The vertex of the quadratic will be explained in more detail in the section, "Graphing Quadratics and Applications. We need two numbers that when added equal -4 and when multiplied equal
