This is part 2 on factoring, and covers how to factor out a negative sign, and also how to recognize opposites such as a - b and b - a.
- How do you factor out the greatest common factor of a polynomial?
- How do you factor out a negative GCF?
- What happens if the greatest common factor is negative?
- How do you factor -6x + 9?
- How do you factor a polynomial if the first term is negative?
- How can you factor -9x^2 - 12x by taking out the GCF?
- How do you know what goes in the parentheses when you factor a polynomial?
- What does -16a^2b + 24ab^4 + 8ab factor into?
- How do you factor a polynomial that has more than one variable?
- How do you factor a polynomial by factoring out the negative greatest common factor?
- How can you factor a -1 from a polynomial?
- How do you factor -3x + 14?
- What does 5x-8 become if you factor our a -1 from both terms?
- How can you factor -3x-16?
- How do you find the opposite of a polynomial such as 3x - 9?
- What is an easy way of writing the opposite of the difference of binomials such as a - b?
- Why does 7y - 8 = -1(8 - 7y)?
This lesson does a bunch more examples of factoring out the GCF. This time, however, the twist is that the GCF of the polynomials is negative. Also discussed is factoring out a -1 and switching all of the signs.
