is q3 supposed to be q³ ? please use correct terminology.11q³ - 7q - 7q³ + 7
4q³ – 7q + 7
you may be able to factor it.
but in this case, the roots are not real. so that is as far as you can go unless you are studying imaginary numbers.

11q^3 - 7q - 7q^3 + 7
= 11q^3 - 7q^3 - 7q + 7
= 4q^3 - 7q + 7
= 11q^3 - 7q^3 - 7q + 7
= 4q^3 - 7q + 7
