Simplifying Rational Expressions... How? (NancyPi)

(x-2)(x-1)/(x+3)(x-2)

x-1/x+3

1-1/3

0/3

x2/x2=1 3x 2x+x/2x+2x+x 2/-6

1 /2x 2/-6

1+2/2x-6

3/2x-6

3/2= 11/2

3/-6 = 1/3

3x/3x+2x= /2x

1+2=3/2x-6

3/2x-6=2+1/2=1/x-6

1/x-6

1/1 x x-6/x-6= x-6/x-6 =1

x=1

15x2-8x-12/-20x2+14x+12

3/-4 4/7 1

3+4-1/-4+7

7-1=6/-4+7=3

6/3=2

You are so gorgeous!! And smart.

យល់ហើយ😊

😇Thanks for the video ! If someone can help me ! A) In the second exercise, why doesn't Nancy also write "x unequal to -6" (after "x unequal 1") ? B) How can we guess numbers y and z in (x + y) (x - z) when we have for example x2 - 3x + 2 ?

Hi just coming across
Can we simply it further with

X+7/2
Multiply both sides by 2
2x+14=0
2x=0-14
2x=-14. (Divide both sides by 2)
X=-14/2
X=-7

Please how can I solve log27 up and 10down ÷ log3up and 10down

You're the best ❤😊

the last simplify number 3 another bracet (2x+1) =0 so we must write x not equal -1/2

You are a great teacher

Hi Nancy. Your math knowledge is impressive. I hope this knowledge led to an amazing career for you.

Come back Nancy

Yo

@NancyPi I have a Math exam in HiSET today!

Hi nancy i am from Egypt and i wonna tell u that u are amazing u simply explaination for mathematics is so great and i am studying at faculty of engineering in egypt an i wonna till u go ahead ❤

👏👍

Its all u have been done just becoz e of practicing...

Dumbass

Im confused, in example #3 -6•2=-12 but -6 + 2 does not equal -8…. So why are you using it?

WHAT DO U MEAN LOL

She talks like she's your friend, but not in an annoying way

ooo look at nancy being sassy

Brah I used the think I was good at math 😅

I’ll never get along with math, sadly😭

😮 OMG ... Thank you, Nancy Pi (π) ... 👍 You're, SUPER-AWESOME ... 😍😍😍
😮 If you ask me if I like this video, I would say, "Does E=mc²?" 🤔
🤔 I'm still trying to figure-out how you write-backwards ... like Leonardo da Vinci.
🧐 SDRAWKCAB 🪞 🤭

no one mentioning the fact she's writing backwards? lol like how?

Thank you Nancy you've helped me a lot i love your explanation,the way you explain is interesting thank you a lot

Thank you for your explanations.. I love how you explain restrictions .I agree we should as you say "responsible" and include the restricted condition. Thank you for sharing your understanding. Love that you are an MIT grad.

You are changing the world through education.

i AM one of the wise ones
