Sal solves the following problem:ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½Given a rectangle with length a^2+6a+27 and width a^2-9, write the ratio of the width to the length as a simplified rational expression.  # Divide polynomials by monomials with remainders

## By Khan Academy

Sal divides (7x^6+x^3+2x+1) by X^2, and writes the solution as q(x)+r(x)/x^2, where the degree of the remainder, r(x), is less than the degree of x^2.  # Divide polynomials by linear binomials with remainders

## By Khan Academy

Sal divides (x^3+5x-4) by (x^2-x+1) using long division.  # Dividing decimals 2

## By Khan Academy

When dividing a whole number by a decimal, you're going to need to change that decimal into a whole number. How? We'll show you.  # Dividing decimals 2

## By Khan Academy

The old saying is practice makes perfect. Let's keep practicing dividing decimals and making our divisor a whole number.  # Polynomials

Divide x2-2x-8 by x+2 (same as the example above).  # Area models to visualize division using place value | 4th grade | Khan Academy

## By Khan Academy

We can break up big division problems into smaller, easier problems. In this video, we solve 268 divided by 2 and 856 divided by 8.  # [5.NBT.2-2.0] Multiplying/Dividing by 10 - Common Core Standard
