Greatest Common Factor

Class members investigate the effect of a negative scale factor dilation on coordinate shapes as they watch a short video that shows an example of a geometric figure undergoing a dilation with a negative scale factor. Learners then try a...

Is it bigger, or is it smaller—or maybe it's the same size? Individuals learn to describe enlargements and reductions and quantify the result. Lesson five in the series connects the creation of a dilated image to the result. Pupils...

Sal explains that the greatest common factor of any number is the largest number divisible into both monomials and not necessarily the number with greatest value. He breaks down two numbers into their prime factors as a product of its...

Use division and factoring to determine the leading 1 coefficient. This presentation thoroughly explains how to factor a trinomial in order to determine its common factors.

Sal takes polynomial equations in the other direction with this video where he shows how to factor them instead of adding or multiplying them. He has two goals in this activity: first, to show how to factor polynomial equations, and then...

Model how to find the greatest common factor of monomial expressions with a video that works through three examples. The first is a constant, the second a single variable expression, and the third is a multivariable example.

So you are looking for all the possible binomial factors of a trinomial expression? First find the factors of the coefficients. Then set up a table or template to do a guess and check. Write out, using the template, all the possible...

Enlargements make it bigger, right? A video shows viewers how to perform a basic dilation with a fractional scale factor. They learn how to use the scale factor to find the location of the transformed vertex by multiplying the horizontal...

How will a scale factor affect a figure—negatively? Using a grid, the narrator of an engaging video performs a dilation with a negative scale factor. The presenter compares a positive scale factor with a negative scale factor to explain...
