Question

how do you simplify this ...
x^3+1

Answer 1

you cannot "simplify" it
you can, however, factor it

Answer 2

\(\LARGE{x^3+1=??}\)

Answer 3

you can use \(a^3+b^3=(a+b)(a^2-ab+b^2)\) with \(a=x,b=1\)

Answer 4

Do you mean factorise x^3 +1 = 0?

Answer 5

but there is no way that the factored form is any "simpler" than \(x^3-1\)

Answer 6

or even \(x^3+1\) it is just a different form

Answer 7

can you expand it??

Answer 8

it is already expanded

Answer 9

standard form is \(x^3+1\) factored form is \((x+1)(x^2-x+1)\)

Answer 10

@Lulu212 perhaps you are getting this confused with \((x+1)^3\) which you can expand
