1. Repetitive multiplication.
When you multiply like bases you add the exponents.
When you divide like bases you subtract the exponents.

2. A non-zero base to the power of 0 = 1.
A power to a power, multiply the powers.

3. Simplify by using all exponential properties and positive exponents.

4. Negative exponents moves the base from the top to the bottom or bottom to the top.
Write using positive exponents. Simplify, if possible.

5. Use exponent properties and write using positive exponents
Use exponent properties and write using positive exponents. Simplify, if possible.

6. Place the decimal point to create a number between 1 and 10.
Count the number of decimal places, this is the power on 10.
Notice that the power is negative!
Exponent sign rule.
Original number > 1, Positive exponent.
Original number < 1, Negative exponent.

7. Multiply like bases of 10, add the exponents

A one term polynomial.
3x2 7x
2xyz 6
2xyz – 6
A two term polynomial.
3x2 + 7x
3x2 + 7x – 6
A three term polynomial.

9. The sum of the powers on the variables in one term.
2 + 3 = 5, 5th degree
The term with the highest degree will be the degree of the polynomial.
The value that is multiplied to a variable in a term.
The term with the highest degree will be the leading term of the polynomial ONLY if the polynomial consists of one variable!
The value that is multiplied to the leading term.
Polynomials that consists of one variable are traditionally written with the powers on the variable in descending order. This way the leading term is written first in the polynomial. Below 3x2 is the leading term, 3 is the leading coefficient, and the polynomial is a 2nd degree.
3x2 + 7x – 6

Cancels
Binomials with the same 1st terms, but opposite 2nd terms are called CONJUGATE PAIRS. The middle terms always cancel. ( a + b ) ( a – b ) = a2 – b2. Just multiply F and L.
“2x * 2x”
“5 * 5” * * *
Dble IT
Binomials that are squared need to written twice and FOILed.
“2x * 5 = 10x Dble IT”
Do you see a pattern?
Do see the SMILE?
The middle terms are always the SAME. When we combine them, it DOUBLES.
( a + b )2 = a2 + 2ab + b2 or ( a – b )2 = a2 – 2ab + b2. Mr. Fitz does the SMILE technique.

Because the powers are the same, we can move the -2 and 5 into the ( )’s and make it -10 which is easier to multiply by!
It will help to keep variables in alphabetical order to better recognize the same powers on the variables
