Explanation & Answer

Thank you for the opportunity to help you with your question!

3x^2-9x+3

=3x^2-3*3x+3*1

=3(x^2-3x+1)      we take 3 out from all the terms.

Last term is product of 3 and 1. When 3 is taken out, 1 is left.

Please let me know if you need any clarification. I'm always happy to answer your questions.
