Question about the last problem (5x²-4x=6): Why can't we just change 2√34 to a decimal? When I do that I get x=1.6 and x= -0.8 as answers. Are those answers wrong? Tia.

I'm getting it! Just keep messing up with the negative signs 🤦 need to get the hang of those with this formula. Its just so much is happening you forget the small details. Sometimes I try to solve before you. And I did 1 - 288 I forgot to turn it into a + and it messed everything up. Didn't get a even square root or anything lol.

Yay for "getting it"!!! What an awesome feeling. Yes, losing negatives is a very common student issue. I often joke that I haven't yet met a student who's bad at algebra but I've met plenty who were crappy secretaries. The good news is, with repetition, you will make those types of errors less and less.

So watched this again lol. Got them all right! But for the last question I reduced everything even the number in the radical sign. 34 to 17 😂 well guess I wasn't supposed to do that. So we reduce everything if they have the same factor but don't reduce inside the radical sign. Got it now
@LightandSaltLearning5 жыл бұрын
Exactly. Whole numbers reduce with whole numbers. Radicals can reduce with radicals, but since the quadratic formula doesn't have radicals in the denominator, that wouldn't be an issue. Be careful though. You can only reduce if you can pull a factor out of EVERY term. If the radical doesn't have a whole number out front, you won't be able to reduce anything. Does that make sense?

So if the there isn't a perfect squre root then it's a (i) answer? So they'll probably just give perfect square roots on the GED test with this?
@LightandSaltLearning5 жыл бұрын
There are actually a few possibilities. If it's a perfect square inside the radical, you'll get two rational answers (whole numbers or fractions), if it's a positive number inside the radical, you'll get answers that still have radicals, if its negative inside the radical, that's when you'll see imaginary numbers (i). I've seen both tofu the first two scenarios come up on the GED. Haven't seen or heard of a complex (with an i) yet but that doesn't mean it couldn't happen.

So for the experienced worksheet on your site, there were a few errors that kind of confused me and left me questioning my math for way too long lol. Question #3 is missing a variable. So when I attempted to work through the problem the way it's written, I got "no solution" and it's not matching up to the answer posted. I tried adding the missing variable and got the same answer you posted. And then the answer to question #5, is not matching up to the answer I get when I work through the problem. In the answer posted, the number inside the radical is not correct. The number is 13 when it should be 17. I spent 20 minutes trying to rework and redo the problem to match the answer posted only to find out by googling the problem and realizing I was right the whole time and the answer was just a typo lol. Just a heads up for anyone questioning themselves. Don't freak out.

The "enter" key works as an equal sign in the TI. Expert tip, when using the TI to simplify the quadratic formula, make sure you are in "Mathprint mode", and press the n/d fraction button first, then type in the rest of the expression.

That's ok! Don't feel bad about rewatching videos. Be sure you do one worksheet for each video to test your comprehension.
