 Apr6 asked High school math definition of a variable: the first step from the concrete into the abstract… Apr5 comment Factor $14x^2 - 17x + 5$. @TheChaz How do the "issues" you mentioned at the beginning of your answer relate to the quickness and time saving value of the trial and error method? (Provided that students are taught a systematic method.) Apr5 comment Factor $14x^2 - 17x + 5$. I appreciate your comments. Doesn't the trial and error method make you appreciate the group and factor method? Some, who are practiced with the trial and error method, can quickly "see" the factored form. They run through the combinations of factors of the a and c terms and find the factors of the trinomial. They actually prefer this method, and only use the group and factor method when they get stuck. It saves them time. Thanks for the comments.

I'm not defending the teachers answer, but you can have a one sided argument if you talk in circles, therefore a circle has one side. Mar23 awarded Student Mar23 asked Factor $14x^2 - 17x + 5$.
