Key concepts

3 concepts

  1. 1

    When using the quadratic formula, it is important to rearrange the equation into standard form, which is ax² + bx + c = 0.

  2. 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. 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.
