Factoring Expressions 7.EE.1

What do these terms have in common? 4x and 8x -5x and -10x² 8xy and 9x²y² -2xy and -4x² 7y and 10y²

Now you try! 5x and 15x 7x² and 3x -4x²y and 4x 3xy and 6x²y² 6xy² and 18x²y

Factoring Expressions Find the numbers and variables that each term has in COMMON. Ex: 3xy + 6x Common factors: 3x 2) Write the common factors outside of the parentheses. Ex: 3x( ) 3) Write the numbers or variables that are left over inside the parentheses. Ex: 3x(y + 2) DIVIDE 4) Check your answer using the distributive property. Ex: 3x(y) = 3xy and 3x(2) = 6x so, you end up with what you started with 3xy+6x

Factor each of the following: 5xy + 10y 4x + 6xy

Factor each of the following: 5xy + 10y 4x + 6xy

Factor each of the following: 4x² + 5xy 2) 3x²y + 7x

Now you try! 3x + 6xy -4x + 8x² 2xy + 14x
