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

See this example:

- # import complex math module.
- import cmath.
- a = float(input(‘Enter a: ‘))
- b = float(input(‘Enter b: ‘))
- c = float(input(‘Enter c: ‘))
- # calculate the discriminant.
- d = (b**2) – (4*a*c)
- # find two solutions.

## How do you code an equation in Python?

Equations

- In [1]: from sympy import symbols, Eq. x = symbols(‘x’) eq1 = Eq(4*x + 2)
- In [3]: x, y = symbols(‘x y’) eq2 = Eq(2*y – x, 5)
- In [4]: x, y, z = symbols(‘x y z’) eq2 = Eq(2*y – x – 5) eq3 = eq2. subs(x,z) eq3. Out[4]: Eq(2*y – z – 5, 0)

**Where is quadratic programming used?**

QP is widely used in image and signal processing, to optimize financial portfolios, to perform the least-squares method of regression, to control scheduling in chemical plants, and in sequential quadratic programming, a technique for solving more complex non-linear programming problems.

**What is meant by quadratic programming?**

Quadratic programming (QP) is the process of solving certain mathematical optimization problems involving quadratic functions. Specifically, one seeks to optimize (minimize or maximize) a multivariate quadratic function subject to linear constraints on the variables.

### Is SVM quadratic?

A new quadratic kernel-free non-linear support vector machine (which is called QSVM) is introduced. The SVM optimization problem can be stated as follows: Maximize the geometrical margin subject to all the training data with a functional margin greater than a constant.

### What is SMO in machine learning?

Sequential minimal optimization (SMO) is an algorithm for solving the quadratic programming (QP) problem that arises during the training of support-vector machines (SVM). It was invented by John Platt in 1998 at Microsoft Research.

**How to do quadratic formula in Python?**

Install and set up Python. Visit www.python.org and download the latest version of Python for your device (Windows,macOS,Linux).

**Why you should learn Python programming?**

Python is Interpreted − Python is processed at runtime by the interpreter.

## How can I start programming in Python?

the “Run” menu. When you do this the program will start running, and any output it produces—anything it says or does or prints out—will appear in the Python shell window (the other window, the one that appeared ﬁrst). In this 4Note that you can have several windows open at once, including the Python shell window
