can you show me the steps please
some.random.cool.kid
  • some.random.cool.kid
not the answer

  • SolomonZelman
like terms; examples: \(\large\color{black}{ \displaystyle 2x^2+3x^2=5x^2 }\) \(\large\color{black}{ \displaystyle 9x^w-8x^w=1x^w=x^w }\) \(\large\color{black}{ \displaystyle 2y-5y=-3y }\) \(\large\color{black}{ \displaystyle 14+13=27 }\)
SolomonZelman
  • SolomonZelman
those are examples of the terms you can combine (their coefficients - the numbers in front of the variable - don't matter. And the like term is defined if there is a same variable and it is raised to the same power.)
some.random.cool.kid
  • some.random.cool.kid
where did you get 8x?
SolomonZelman
  • SolomonZelman
but you can NOT combine (examples) \(\large\color{red}{ \displaystyle 3x^4+2x^3 }\) (although variable is same, the powers of x are NOT the same) \(\large\color{red}{ \displaystyle 2x^p+3a^p }\) (although the powers of the variable are the same (power of p), because variables are NOT the same.) \(\large\color{red}{ \displaystyle 5+3x }\) (one term contains variable, the other term does not)
SolomonZelman
  • SolomonZelman
@some.random.cool.kid I didn't get 8x. these that I posted are just examples.
some.random.cool.kid
  • some.random.cool.kid
can you make the examples for my equation?
some.random.cool.kid
  • some.random.cool.kid
i want to know how the equation would be set without any answer @SolomonZelman
some.random.cool.kid
  • some.random.cool.kid
@sleepyjess can you help me too
SolomonZelman
  • SolomonZelman
ok, I will highlight each like term in a particular color.

SolomonZelman
  • SolomonZelman
is this better?
some.random.cool.kid
  • some.random.cool.kid
i solved it already
some.random.cool.kid
  • some.random.cool.kid
was i correct
some.random.cool.kid
  • some.random.cool.kid
its above
SolomonZelman
  • SolomonZelman
no, it is not correct
SolomonZelman
  • SolomonZelman
I wrote it an order better to see just now
some.random.cool.kid
  • some.random.cool.kid
5x^2 - 7x + -4 =?
SolomonZelman
  • SolomonZelman
-2+9=-7 or +7?
some.random.cool.kid
  • some.random.cool.kid
thats the answer when i combined them now i must solve this
SolomonZelman
  • SolomonZelman
-2 + 9 = -7 or +7 ?
some.random.cool.kid
  • some.random.cool.kid
its 7x
SolomonZelman
  • SolomonZelman
yes

some.random.cool.kid
  • some.random.cool.kid
i solved that part already so from there whats next
SolomonZelman
  • SolomonZelman
this is it
SolomonZelman
  • SolomonZelman
you don't need any work, you combined all the like terms, and now this polynomial is written in a simple form.
SolomonZelman
  • SolomonZelman
simplest* form

yw
some.random.cool.kid
  • some.random.cool.kid
thank you very much i have one mor
some.random.cool.kid
  • some.random.cool.kid
can i put it @SolomonZelman

  • SolomonZelman
can you put it?

8x^2 – 5x – 2 + 7x – x^ + 3
SolomonZelman
  • SolomonZelman
oh, another question? I thought you were referring to the answer to this question. Sure, go ahead and post it here.
SolomonZelman
  • SolomonZelman
\(\large\color{black}{ \displaystyle 8x^2 – 5x – 2 + 7x – x^2 + 3 }\) like this?
some.random.cool.kid
  • some.random.cool.kid
ok next is 12x right
some.random.cool.kid
  • some.random.cool.kid
because 5x and 12x combined
some.random.cool.kid
  • some.random.cool.kid
7x*
some.random.cool.kid
  • some.random.cool.kid
and 5 because of 2 + 3
SolomonZelman
  • SolomonZelman
how many x^2 is there?
some.random.cool.kid
  • some.random.cool.kid
two
SolomonZelman
  • SolomonZelman
\(\large\color{black}{ \displaystyle 8x^2- 5x - 2 + 7x - x^2 + 3 }\) \(\large\color{black}{ \displaystyle 8x^2 - x^2- 5x + 7x - 2 + 3 }\)
some.random.cool.kid
  • some.random.cool.kid
12x and 5
SolomonZelman
  • SolomonZelman
-5+7=12 ??
SolomonZelman
  • SolomonZelman
or does -5+7 =2 ?
some.random.cool.kid
  • some.random.cool.kid
2
some.random.cool.kid
  • some.random.cool.kid
@SolomonZelman what about the x^2 - 8x^2
some.random.cool.kid
  • some.random.cool.kid
2x and 5 now what about the 8 part? @SolomonZelman
some.random.cool.kid
  • some.random.cool.kid
hurry
SolomonZelman
  • SolomonZelman
8x² – 5x – 2 + 7x – x² + 3 8x² – x² + 7x – 5x – 2 + 3 7x² + 2x + 1
