CS377: Database Design - Quadratic Formula in Python (3 Points)

Developed by Professor Tralie and Professor Mongan.

Exercise Goals

The goals of this exercise are:
  1. To write mathematical expressions in Python
  2. To write a function that computes an expression and returns its result
Write a function that computes one of the roots of a quadratic equation. In addition to multiplying b by itself, you can compute b*b using the b** with the ** operator. The math.sqrt() method takes a single parameter, which is the number whose root should be computed, and returns the result. Now complete the code to compute one of the roots of the quadratic formula

Quadratic Formula



For reference, the quadratic formula is:



\[\frac{-b \pm \sqrt{(b^{2} - 4ac)}}{2a}\]



given an equation:



\[ax^{2} + bx + c = 0\]



In this exercise, you can simply compute one of the roots, as follows:



\[\frac{-b + \sqrt{(b^{2} - 4ac)}}{2a}\]
