It’s just Division!• The polynomial we divide with is called

The Dividend• The polynomial we divide by is called

The Divisor• The answer is called

The Quotient

Let’s start

Let’s divide x2 + 4x + 4 by x + 2 :

x2 + 4x + 4

x + 2

Use the Long division

How to fill in as to start?

First, write the dividend inside.

Next, write the divisor outside.

Then, divide and the Quotient will be up.

Divisor Dividend

Quotient

Now Divide ...

x2 + 4x + 4x + 2

You divide the first monomial from the Dividend by the first monomial from the Divisor. You write the answer in the Quotient’s place.

x2 ÷ x = x

x

Multiply the answer x by the Divisor

x

x2 + 4x + 4x + 2

x2 + 2xWrite the

answer under the dividend

and subtract it from the dividend.

0 + 2x + 4

Not finished, continue the Division

x2 + 4x + 4x + 2

x

x2 + 2x

2x + 4Repeat the

same steps…

Divide 2x by x

+ 2

2x ÷ x = 2

Finish it!

x2 + 4x + 4x + 2-x2 - 2x

2x + 4

x + 2

Multiply 2 by the divisor.

2x + 4

0Subtract

and answer.

Finally…

x2 + 4x + 4

x + 2= x + 2
