Question

Simplify:



4x^3 – 3x^2 + x + 3x^3

Answer 1

Combine the like terms.

Answer 2

but the x's .. ?

Answer 3

$$ 4x^3 – 3x^2 + x + 3x^3 $$
There are two terms that a like terms so you can combine them.
They belong to \(x^3\).
Rewrite the equation so it look easier to combine:
$$ 4x^3 + 3x^3 – 3x^2 + x \implies 7x^3 – 3x^2 + x$$

So that is as much as you can simplify it, do you understand?

Answer 4

I think i understand.. so it's 7*x^3-(3*x^2)+x ?

Answer 5

The round brackets are unneeded.

Answer 6

Okay thank you ! :)
