Thank you for the opportunity to help you with your question!
so we are looking for a number that adds into -1 and multiplies into -6
which in this case is -3,2 -3+2=-1 and -3*2=-6
and since the first number is a one remember there is an invisible 1 infront of x^2 you get
(x-3)(x+2) FOIL it to verify
Please let me know if you need any clarification. I'm always happy to answer your questions.
