December 9th, 2016

2. *When we solve equations for x, we typically are trying to find only real number solutions. Recall that real numbers are numbers that don’t contain the imaginary component

3. Ex. 1: Solve each equation for x.b) c) d)

4. So how do you know when a quadratic equation has one, two, or no real solutions?
How do you know when a quadratic equation has rational solutions?

5. Ex. 2: The surface area of a cube with sides of length x is given by
Ex. 2: The surface area of a cube with sides of length x is given by If the surface area is 80 square feet, what is the side length x? You may round your answer to the nearest hundredth, if necessary.
