Grouping for Factoring: Group the terms into two pairs to prepare for factoring by grouping. Group the first two terms and the last two terms separately. 6z3−3z2 and −16z+8
Factor First Group: Factor out the greatest common factor from the first group.The greatest common factor of 6z3 and 3z2 is 3z2.3z2(2z−1)
Factor Second Group: Factor out the greatest common factor from the second group.The greatest common factor of −16z and 8 is −8.−8(2z−1)
Common Factor Observation: Observe that both groups now have a common factor of (2z−1).Write the expression as a product of (2z−1) and another factor.(3z2−8)(2z−1)
