Find the solution to the following problem.

 3x219x    +     x2-x   

x2-25        (x+5)(x-5)

  4x2-20x       or       4x         x ≠ -5,5

(x+5)(x-5)              x+5

This should be your first instinct when given a rational function.

What is factoring?

Find the product of the following problem.

 x2-6x+8     x       10   

    2x-2               x-4

 10(x-2)      or     5(x-2)        x ≠ 1,4

  2(x-1)                (x-1)

200

This is the third and final step of multiplying rational functions (Ms. Deffenbaugh likes to call it the CC rule).

What is Combine & Cancel?

The restrictions of the following problem.

x2+2x-24   x         1       

    x-4              x2-6x+8

What is x≠2,4?

This is the step you need to perform on a division problem right after you factor.

What is flipping the second fraction and changing from division to multiplication? 

300

These are the steps, in order, of multiplying rational functions.

(Hint: These steps were written by authors to a mini book...)

What is factor, write restrictions, and combine & cancel?

300

This is the only operation where you flip one of the rational functions.

What is division?

300

This is Ms. Deffenbaugh's two most important rules of math.

(Hint: Rule #1 can cause destruction of something, and Rule #2 is the first step of the process that is your BFF in math)

What is "#1: You can't divide by zero" and "#2: The first step of factoring is to factor out the GCF"?

This is the process of factoring the following expression.

4x2+8x+4

What is factoring out the GCF of 4 (being left with x2+2x+1 in parentheses), then finding factors of 1 that add to be 2? Factored Form: 4(x+1)(x+1).

400

This is why we have restrictions in rational functions.

What is "because they make the denominator zero, and you can't divide by zero"?
