Group Terms: Look for common factors in pairs of terms.We will group the terms into two pairs and look for common factors in each pair.Group 1: 3y3+2y2Group 2: 15y+10
Factor First Group: Factor out the greatest common factor from the first group.The greatest common factor of 3y3 and 2y2 is y2.So, 3y3+2y2=y2(3y+2)
Factor Second Group: Factor out the greatest common factor from the second group.The greatest common factor of 15y and 10 is 5.So, 15y+10=5(3y+2)
Write Factored Groups: Write the expression with the factored groups.Now we have:y2(3y+2)+5(3y+2)
Factor Common Binomial: Factor out the common binomial factor.Both terms have a common factor of (3y+2).So, y2(3y+2)+5(3y+2)=(y2+5)(3y+2)
