3rd Degree Polynomial Long Division Calculator

What is 3rd Degree Polynomial Equation Division?

Imagine you have a long math problem with lots of x's and numbers. A 3rd degree polynomial is like that - it has x's with powers up to 3. When we divide these long math problems, it's like sharing a big sandwich among friends, but with numbers!

How to Calculate 3rd Degree Polynomial Equation Division

We divide polynomials just like we divide numbers, but we have to be careful with the x's. We start with the biggest x (x^3) and work our way down, just like when we share that big sandwich, we start with the biggest pieces first!

Formula

A 3rd degree polynomial looks like this:

\[ ax^3 + bx^2 + cx + d \]

Where:

• \(a, b, c,\) and \(d\) are numbers
• \(x\) is our variable (like a placeholder for any number)
• The highest power of \(x\) is 3

Calculation Steps

1. Write out your long polynomial (dividend) and the shorter one you're dividing by (divisor)
2. Divide the first term of the dividend by the first term of the divisor
3. Multiply the result by the divisor
4. Subtract this from the dividend
5. Bring down the next term
6. Repeat steps 2-5 until you can't divide anymore
7. What's left is the remainder

Example and Visual Representation

Let's divide \(x^3 + 4x^2 + 0x - 5\) by \(x + 2\)

Here's how it looks step by step:

In this picture, we see how we divide step by step, just like sharing that big sandwich. We keep dividing until we can't anymore, and what's left (3) is our remainder!
