According to Wikipedia,

In mathematics, a **polynomial** is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

Nickzom Calculator is the very first calculator encyclopedia to come out from Nigeria. It is capable of solving over 50,000 calculations and presenting the steps (workings). Fortunately, **Nickzom Calculator** can compute conception and best intercourse dates.

You can access Nickzom Calculator via any of these means:

For Nickzom Calculator, there are two polynomials which are **cubic** and **quartic.**

A cubic equation or polynomial has a degree or order of 3 whereas a quartic equation or polynomial has a degree or order of 4.

Let’s start with a **cubic equation**

Find the roots of f(*x*) = 2x^{3} + 3x^{2} – 11x – 6 = 0, given that it has at least one integer root.

From the example above, you can see that the **coefficient of x ^{3}** is 2, the

**coefficient of x**is 3, the

^{2}**coefficient of x**is -11, the

**constant before the equality sign**is -6, the

**constant after the equality sign**is 0.

Now, click on **Calculate**

From **Nickzom Calculator** – The Calculator Encyclopedia, the values of x are: 2, -0.5 and -3.

Now, let me show you how to use Nickzom Calculator – The Calculator Encyclopedia to get answers for a **quartic equation**.

Find the roots of f(*x*) = 3x^{4} + 6x^{3} – 123x^{2} – 126x + 1080 = 0, given that it has 4 real roots.

From the example above, you can see that the **coefficient of x ^{4}** is 3, the

**coefficient of x**is 6, the

^{3}**coefficient of x**is -123, the

^{2}**coefficient of x**is -126, the

**constant before the equality sign**is 1080 and the

**constant after the equality sign**is 0.

Now, click on **Calculate**

From Nickzom Calculator – **The Calculator Encyclopedia**, the values of x are: 3, -4, 5, -6.
