Our teacher was on some rant about political stuff and then just gave us our math homework without explaining it and it's a NEW CONCEPT.
can someone explain how to simplify the term x2(x+1) with steps?

distribute the 2 so it's x * 2x + 2 then combine the like terms, so it's 3x +2 (I THINK)

i dont really know how to explain it, but if you have 2(x + 1) you can use the distributive property and, like, distrubute... so you multiply the 2 by each part of the equation in the parenthesis, so you have 2x + 2*1 which is 2x + 2

x2(x+1)
do you mean 2x? no such thing as x2.
it'd be 2x(x+1)
then, multiply the x and the 1 in the parentheses
the answer would be 2x + 2
note, if the number outside the parentheses is not grouped with a variable (i.e., 2 instead of 2x)
it'd still be the same.

@ex it is possible to have x2. you just don't like the way it looks. i don't either. it's the same as x * 2

no, that's technically incorrect because you aren't writing it correctly
and x times 2 is still x2
also, your dad is wrong.

Stop lying to the kid....
use this website for help:

The answer is already simplified... if you want to distribute it then it would be

2x^2+x
pronounced: Two x squared plus x

@ex it's just another way to write it. if that's the way the problem was written, then they mean x * 2. my teacher has written it like that before
