In problem 3 why only take x but not 3x ? with 3x it works it will give us -------> 3x (3x^2 - 4x + 2) can I use your method as an alternative to polynomial long division ?
I have another question is the quadratic polynomial roots are imaginary or complex roots. Is their another method to find the roots instead of Quadratic formula ? For example, what are the roots of this quadratic polynomial: 3x^2 - 4x + 2 ?
No, he didn't get it wrong, he got it right.... whether you factor out 3x, or just 3, or just x, whether you partition the trinomial into 9x^3/2x - 12x^2/2x + 6x/2x and simplify, you will get the SAME RESULT. You see, in math there are many different ways to solving problems and arriving to the same answer. Nonetheless, no matter how you solve the answer, if you follow the steps correctly you will get the same results... that's what makes math so reliable.
dude I'm an 11th grader studying for a test on rational expressions for tomorrow and I don't understand anything. Take a chill pill and enjoy the 7th grade. What are you learning in class right now? Integers? Damn kid, you're doing better than I am.
@@asdasdasd-g5u ah, that changes everything. Because in asian countries like china, india, korea, and japan, mathematics is taken every semester of every year, which is why you are ahead. I am from Canada so we only have math once a year.
At 5:42, the restriction should be x can't be -3!!
@AllThingsMathematics I do understand now!
6:38 Would it work to take out 3x from the numerator instead of only taking out x?
True but it works out to be the same answer tho.
you teach well and have a great site. you should definitely cover functions & adv function in its entirety if you haven't already.
why can you not take out 3x on the last rational expression question in the numerator?
^^^???

Thanks a lot professor for your videos. I follow you from Algeria.
Do you factor out Least Common Multiple (LCM) or Greatest Common Factor (GCF)?
GCF
Thanks for the tips, you probably saved me
wait i don't understand how you got that at 4:14
Maybe 2x and 5x is same variables then you had to simplify fractions! 4:15.
Hi. For the second question isn't the restriction x can not equal -3, instead of positive 3
He made a writing error but you can hear him say negative 3.
@@justiceb9766 thanks
in the restriction of the second one x deosnot eqaul to - 3 not to 3
ughhhhhh lolll........yea I screwed up, thanks for pointing it out!
You are amazing 👏
the answer for 3 is, 3(3x^2-4x+2)/2
Can anyone else just not focus on the what he’s trying to teach? Orrrr..😭😭

You got the #3 wrong. when you factor the numerator is 3x (3x^2-4x+2)/2x

wait i am a grade 7 and how am i studying this already
