Simplify \[2n^2 - 4n * 5n - 10n^2 + 4\] A. \[8n^2 + n + 4\] B. \[- 24n^2 \] C. \[- 28n^2 + 4\] D. \[10n^3 - 10n^2 - 20n + 4\] PLEASE HELP
one approach regroup and factor
im in 6th grade so i have no idea what this question is about
wait this is even simplier they just want you to add like terms
you need to simplify the equation by combining elements with the same variable. if it's just a letter, it's 1*the variable. You also combine numbers.
Does that help?
i dont know
ok i understand that but i dont understand how to simplify it all down to where i can find the answer
if that makes sense
you have to read the responses. what is 2 - 20-10 =
is it -28
what is -28*n^2
what is n is it a certain number
so what is it for
in algebra we use letters and numbers just an entity
so do i just ignore it
it exists you can't just ignore it
so what do you do with it
sorry im not good with anything algebra
-28*n^2 = -28n^2
do you see all we did was group like terms and simplify?
i guess so. i feel soooooo stupid right now
don't. you just need to try.
but i have it just doesnt ever seem to work
clear the negative things from your mind and you will have room to absorb the new material more easily.
you are here to learn and we cannot give direct answers. you need to read the responses given and ask questions about what you do not understand.
ok so how can i solve these quickly because this is due soon
once you learn something practice and you will be able to do the problems faster. this is basic stuff for higher math. all the best.
for now just look at what the question is asking and identify what needs to be done seems like all you are doing right now is grouping like terms
i have like 15 minutes
and like 6 or 7 questions left
well don't panic do 4 right and mark the rest if necessary but always mark something
