Each denominator is factored and then any common factor is used only once and all other unique factors complete the LCD

A demo of this topic where I stack the l ike terms in columns as a perform the distributions connecting each term of the first polynomial to each term in the other.

A quick F.O.I.L. pattern to multiply two binomails. One of the variable terms is negative.

A demonstration of squaring a binomial with radical terms and then a second example showing how conjugate binomials can be multiplied.

Factoring quadratics to find the LCD of two fractions in algebra

A second look at factoring the top and bottom of a fraction in algebra that then reduces that fraction.
|
|
|
This shows how to factor the numerator and denominator of a fraction in algebra so that we can reduce the same factors ono the top and the bottom because they divide to one.

A two step process is shown here. First, as always, look for a greatest common factor (GCF) and remove it from all terms. Then second, the resulting quadratic expresssion can then be factored into…

This is a quadractic equation that can be factored to solve it. The zero product property allows writing the factors each equal to 0 and then solving those linear equatioins.

|
|
This applies the factoring methods learned previously to solving a quadratic equation in standard form, that is with all th eterms on the left of the equals sign and 0 on the right

One of the simpler factoring techniques if you know what you are looking for.

Demonstrates what happens when the F.O.I.L. method is applied to multiply two binomails of the form (a + b) (a - b). It's special circumstance that allows a short cut.
