## Can Python solve polynomial equation?

We often solve polynomial equations in mathematics to find the roots of the equations.

**How do you find the roots of a polynomial in Python?**

Approach:

- Apply function np. poly1D() on the array and store it in a variable.
- Find the roots by multiplying the variable by roots or r(in-built keyword) and print the result to get the roots of the given polynomial.

### How do I get root in Numpy?

sqrt() in Python. numpy. sqrt(array[, out]) function is used to determine the positive square-root of an array, element-wise.

**How do you take the input of a polynomial in Python?**

This code will be used to take input of the polynomial as y for instance. y = x**2 + x*4 and it takes input of x as float value like if i give 2 for x then this expression will prints 12.

## How do you solve a polynomial of degree 2 in Python?

- Example 1. With python we can find the roots of a polynomial equation of degree 2 ($ ax ^ 2 + bx + c $) using the function numpy: roots.
- Example 2. Another example with $x^2+3x=0$ >>> coeff = [1,3,3] >>> np.roots(coeff) array([-1.5+0.8660254j, -1.5-0.8660254j])
- Example 3.
- References.

**How do you make a tic tac toe game in Python?**

Steps to Build a Python Tic Tac Toe Game

- Create the display window for our game.
- Draw the grid on the canvas where we will play Tic Tac Toe.
- Draw the status bar below the canvas to show which player’s turn is it and who wins the game.
- When someone wins the game or the game is a draw then we reset the game.

### How do you write a polynomial equation in Python?

Write a Python function eval_polynomial(p, x) that returns the value of P(x) , where P is the polynomial represented by the list of its coefficients p . For example, eval_polynomial([1, 0, 3], 2) should return 1*2^2 + 0*2 + 3 = 7. Use a single while loop.

**How do you solve a quadratic equation using Numpy in Python?**

Consider for example the following polynomial equation of degree 2 $ x ^ 2 + 3x-0 $ with the coefficients $ a = 1 $, $ b = 3 $ and $ c = -4 $, we then find: >>> import numpy as np >>> coeff = [1,3,-4] >>> np. roots(coeff) array([-4., 1.]) this equation has 2 real roots: $ x = -4 $ and $ x = 1 $.

## How do you do square root in Python?

sqrt() function is an inbuilt function in Python programming language that returns the square root of any number. Syntax: math. sqrt(x) Parameter: x is any number such that x>=0 Returns: It returns the square root of the number passed in the parameter.
