We learned that quadratic equations can be expressed in both general and standard form.
In this unit, we will be mainly focused on working with the general form!
Remember…
- A quadratic function can cross the x-axis either 0, 1 or 2 times.
- Points where the graph crosses the x-axis are the real solutions, because f(x) = 0.
- The x-intercept are called the real roots of the quadratic function.
Some concepts you should also be familiar with….
- Real zeros of a quadratic function
- Zero factor property
