Quadratic Equation Roots
Write a function to calculate roots of a quadratic equation of the from ax^2+bx+c=0
The formula to find the roots of a quadratic equation is given below:
X+ = (-b + root of (b^2 – 4ac))/2a
X- = (-b – root of (b^2 – 4ac))/2a
Input specification:
Input 1: A double value representing the coefficient value of x^2 in a quadratic equation.
Input 2: A double value representing the coefficient value of x in a quadratic equation.
Input 3: A double value representing the coefficient value of 1 in a quadratic equation.
Output Specification:
Return a double array representing the value of the two roots.
Note: Consider the output root values off to 3 decimal places. Assume all roots are real.
Example 1:
Input 1: 1
Input 2: -2
Input 3: -3
Output: {3.0,-1.0}
Explanation:
On substituting the values of a,b and c in the formula, the roots will be as follows:
x+ = 3.0
x- = -1.0
Example 2:
Input 1: 2
Input 2: 4
Input 3: 1
Output: {-1.707, -0.293}
