- How do you factor a trinomial that does not have a leading coefficient of 1?
- How do you factor 2x^2 - 7x + 3?
- How do you figure out what numbers go in parentheses when factoring a trinomial?
- How do you know whether to add or subtract when you factor a trinomial?
- How can you check to see if you factored a trinomial correctly?
- How do you factor 5x^2 - 13x - 6?
- What do you do when you plug numbers into parentheses to factor a trinomial and it does not work?
- How would you factor 2x^2 - 5x + 2?
- What happens when you are factoring if the middle term is negative and the last term is positive?
- How can you decide if 5x^2 + 33x - 14 = (x - 7)(5x + 2)?
- How can you decide if 18x^2-27x+4=(3x-4)(6x-1)?
- How do you know if 6x^2 - 7x + 3 factors into (3x+1)(2x-3)?
This lesson starts the process of explaining how to factor a trinomial of the form ax^2 + bx + c. These problems are some of the most difficult for students to master. This is a great starting video for factoring complex trinomials.
