@jlobz_8128 3 года назад

tip: you don't need to solve all 3 regions, just solve the one on the left. once you solve it, then the region to the right will always be the opposite sign of what the first one is and so on

@kiwistuffypistachio2558 3 года назад

I’m gonna comment on this so I can remember

@mistadude 3 года назад

You can also solve the one on the middle or the right too the right might be easiest

@reallybad7062 3 года назад

Another tip: sometimes inequality can have more than 3 sections. Just make sure you solved all your roots, then you can assume.

@sirdele 3 года назад

i always check 0 and then one of the regions checks out

@sarmadsultan7981 3 года назад

In factoring by grouping, what if the groups we're left with aren't the same? I ended up with x^2(x+10) - 1(11x+180) from x^3 + 10x^2 - 11x - 180

@castlerock7423 2 года назад

Ok, I have a question. Instead of using the Rational Zeroes Theorem and then moving to Synthetic division, why didn't you just use Synthetic division to begin with as it gave you the remaining factors of the Quadratic? Wouldn't it be easier to do it that way? Also, I just wanted to say thank you for being here. You're wonderful.

@Pianomantodd1 5 лет назад

What happens if your factors are the same (and are less than zero) and it's NOT also "equal to zero" (in a "less than" situation, or vice versa)? (x-3)(x-3)

@castlerock7423 2 года назад

She didn't specify the use of the term "test numbers" which are the numbers inside each interval that was created using the zeroes (or whatever number amounts to the inequality equaling zero. In this case, the zero would be 3, and the interval notation would have to be (-infinity, 3) because if you take one factor of the above you have x-3
