Guided Notes
3 key concepts
- 1
When using the quadratic formula, it is important to rearrange the equation into standard form, which is ax² + bx + c = 0.
- 2
If the quadratic equation is not in standard form, you can either rearrange the terms or carefully identify a, b, and c by paying close attention to the details.
- 3
If you end up with a negative number under the square root in the quadratic formula, it means there is no solution because the graph has no x-intercepts.
