9: when you expand the thing out whats the higesht power of x?
do you know pascals triangle
for 14 you can replace "a" with the big x thing and find which value of the big x is 3
so like you put in a constant
the function subtracts 5 from that constant
finally you divde that by 2 to get 3
idk how to expand it out
i dont understand
jsut think about how many x are muiltipled together
like its (x-5)(x-5)(x-5)
what kind of function is this?
quadratic? cubic? quartic?
idk
im grade 9
bro
do you know a YouTube video
that explains all maths
in 11hrs
or 10
i forgot idk
i wanna watch it
it would be better than being clueless on the homework
daily
so quadratic has two
cubic has three
of the (x-a)(x-b)(x-c) stuff
and quartic has 4
and cubic has degree 3
i dont know of any 11 hour videos sadly
idk how to expand the ^3
then
how
First degree?
@latent patrol do you know any video that teaches all maths
do you know what a polonomial is
you can write all polynomials as (x-a)(x-b)... where a b... etc. are its roots
highest Power of X
and the highest power of x is how many roots it has
now some of these roots might not be real or be the same thing
ye the question is asking for the highest power of X
but the basic concept is that
so if you have (x-5)(x-5)(x-5) whats its highest power of x
1
nono
how
okay so if its highest power of x is 1
then it has one root
(x-a)
if its highest power of x is 2
it has two roots
(x-a)(x-b)
So the highest power is 3?
yes
oooo
does that make sense or should i explain it more
but teach says I cant decide the highest power of X while its between brackets
yes
if i expand it
it between brackets right
i have to remove them
means simplify or smth
well not really
if its just asking for the highest power of x
you can tell what it is without expanding it out
beacuse of what isaid here
so the highest power is 3?
for question 9 yes
because a cubic (highest power is 3) can be expressed by three (x-n)s
and this equation has three (x-n)
lots of experience
and also i have better memory than most people so thats an unfair advantage i got
but with lots of practice you too can get very good at anything
wow
one day will come and i will study every piece in math
that’s a bit ambitious
and solve the whole book
but good luck with that :D
and that fucker will be going thru every page watching the right answer on every question
i do NOT lose no beta
bets*
bet me on that
on bro fr
should i close this
well uh you do have some questions you havent gotten yet
unless ofc you got them all
shouldi watch this
2 vids daily
dunno if it’s good
and its down under 50 days
bet
see if watching it helps you learn stuff if not then maybe it’s not for you
We have seen a nice variety of algebraic equations by now, so let's hone in on a specific kind that we will be working with a lot. These are called polynomials. Let's quickly define what they are and some of their properties, so that we can learn all about how to solve them in the next few clips!
Watch the whole Mathematics playlist: http://bit...
should i start by this
sure!
didn't understand none still
but i think
the question no. 9 is just a compressed polynomial right
im not sure about the exact wording and stuff
compressed is opposite of extending
like
(x-1) (x-1) (x-1) extended
(x-1)³ compressed
right
yea fair
@latent patrol
question 8
is ²
you ahve an x^2 on the outside too
is it solved the same way
well the x^2 is technically just (x-0)(x-0)
so you get (x-0)(x-0)(x-3)(x-3)
which is 4 of them!
X^2(x^2+6x-9)^2
then u kinda js ignore the ^2 outside brackets
so the highest power is 2
So its 2nd degree
..?
right
^^
continue what im saying
After allat
the X^2 at the beginning
u just multiply it with every number inside the brackets
so its
so youve expanded (x-3)^2 incorrectly, remmeber its a^2-2ab+b^2 since (-3)^2 is 9
so its x^2-6x+9
once you expand it the ^2 goes away
finally we're left with x^2(x^2-6x+9) when you multyiply the x^2 together you get an x^4 whcih is the highest degree
(x^4+6x^3+9x^2)
doing this is much better
why is there (x-0) tho
So for every Power is a (x-anything)
like
if its
x^3(x-8)^5
the degree is 3+5
?
or is it different
10
(x^2)^5 is x^10 and then multiply that with x^3 and that’s 13
exponent to the exponent you multiply
exponent times exponente you add
