Identify common factors: Look for common factors in pairs of terms.We can group the terms as follows: (7m3−7m2) and (−5m+5).
Factor out first group: Factor out the common factor from the first group.The common factor in the first group is 7m2.7m3−7m2=7m2(m−1)
Factor out second group: Factor out the common factor from the second group.The common factor in the second group is -5").\(\newline\$-5m + 5 = -5(m - 1)\)
Write factored expression: Write the expression with the factored groups.\(\newline\)We have:\(\newline\)\(7m^3 - 7m^2 - 5m + 5 = 7m^2(m - 1) - 5(m - 1)\)
Factor out common binomial: Factor out the common binomial factor.\(\newline\)The common binomial factor is \((m - 1)\).\(\newline\)\(7m^2(m - 1) - 5(m - 1) = (m - 1)(7m^2 - 5)\)
