Identify Common Factors: Look for common factors in pairs of terms.We will first look at the terms m3 and −2m2 to see if there is a common factor.The common factor is m2.m3−2m2=m2(m−2)
Factor Pairs of Terms: Look for common factors in the remaining pair of terms.Now we will look at the terms −8m and +16 to see if there is a common factor.The common factor is −8.−8m+16=−8(m−2)
Combine Results: Combine the results from Step 1 and Step 2.We have found:m3−2m2=m2(m−2)−8m+16=−8(m−2)Now we can factor by grouping since both groups have a common factor of (m−2).(m2−8)(m−2)
Factor Difference of Squares: Factor the difference of squares in the first group.The term m2−8 is a difference of squares and can be factored further.m2−8=(m+2)(m−2)
Write Final Form: Write the final factored form.Combine the results from Step 3 and Step 4 to get the final factored form.(m+2)(m−2)(m−2)
