Correct Answer: 8ab^2

Deg^°

Rad

•Find your GCF
•Place GCF on the outside of parenthesis
•Everything ‘left over’ when dividing by GCF
goes inside parenthesis

Multiple Choice

Factor out the GCF $$12x+27xy$$

• 3(4x+9xy)

• 4(3x+9y)

• 3xy(4+3y)

• 3x(4+9y)

Multiple Choice

Factor out the GCF $$39a^3b^2+52a^2b^3$$

• $$3a^2b\left(13ab+5\right)$$

• $$26a^2b^2\left(a+2b\right)$$

• $$3a^2b^2\left(3a+4b\right)$$

• $$13a^2b^2\left(3a+4b\right)$$

Given 4 terms
Split in half (2 terms and 2 terms)
Take out the GCF for each pair
Inside of parenthesis should be matching
First term is inside of parenthesis second term is outside of parenthesis
