Factoring 7a3+21a214a-7a^3 + 21a^2 - 14a

To factor 7a3+21a214a-7a^3 + 21a^2 - 14a, note that the leading coefficient is negative, meaning the greatest common factor (GCF) should be negative as well. The GCF is 7a-7a. Factoring out 7a-7a changes the signs of the remaining terms inside the parentheses, yielding the final factored form: 7a(a23a+2)-7a(a^2 - 3a + 2).
