Python Coding challenge - Day 395| What is the output of the following Python Code?

 

Step-by-Step Execution:

Importing SymPy Functions

symbols('x'): Creates a symbolic variable x that can be used in algebraic equations.

solve(eq, x): Finds values of x that satisfy the equation.

Equation Definition

eq = x**2 - 4 represents the quadratic equation:

Solving the Equation

The equation can be factored as:

(x−2)(x+2)=0

Setting each factor to zero:

x−2=0⇒x=2

x+2=0⇒x=−2

Output of solve(eq, x)

solve(eq, x) returns a list of solutions:

[2, -2]

This means the equation has two real roots: x = 2 and x = -2.

Final Output

[2, -2]
