Factoring-a way of life in MATH Begin the journey for success in FACTORING Go for it…

How do you factor a Monomial term. Always check for a common factor. Check all NUMBERS first and then all Check all NUMBERS first and then all VARIABLES. VARIABLES. 8X 3 + 2X 2 – 10X 8X 3 + 2X 2 – 10X The common NUMBER (Factor) is 2 The common VARIABLE (Factor) is X Divide each term by 2X So……. 2X(4X 2 + X – 5) is the factored form.

Remember: To factor you look for a common number and/or variable to “divide” out of each “term”. 4X 5 + 8X 4 – 12X X 2 4X 5 + 8X 4 – 12X X 2 There are FOUR “terms” in this algebraic expression. A “term” is separated by a “+” or “-” sign. 4 is the “common” numeric factor and the largest power the variables have in “common” is a “2”. So, let’s “divide” by 4 and subtract 2 from each exponent of “X”. 4X 2 ( X 3 + 2X 2 – 3X 1 + 4) 4X 2 ( X 3 + 2X 2 – 3X 1 + 4)

Factoring Monomial terms #1. X 2 + 2X Answer: X(X + 2) Divided by “X” #2. 4Y Y 2 Answer: 4Y 2 (Y – 3) Divided by “4Y 2” #3. 12W 4 + 9W 2 – 6W Answer: 3W(4W 3 + 3W -2) Divided by “3W” (Remember to SUBTRACT Powers when dividing Variables) Click speaker for sound
