  2. quadratic equation A quadratic equation is anequation that can be written in the form ax2 + bx + c = 0, where a, b, and c are real numbers,with a 0.

  3. discriminant The quantity under the radical in the quadratic formula, b2 - 4ac.

  4. complex number Any number that can be written in the form a + bi, where a and b are real numbers.

  5. imaginary number A complex number a + bi with b  0.

  6. real part The real part of a complex number a + bi is a.

  7. imaginary part The imaginary part of the complex number a + bi is b.

  8. standard form of a complex number The standard form of a complex number is a + bi.

  9. conjugate of a complex number The conjugate of a complex number a + bi is a - bi.
