Question

Subtracting polynomials

Answer 1

Subtract the same degrees only.

Explanation:

When subtracting polynomials, you can only subtract variables from those with the same degree (like term).

For example:

`x^(2) -x^ = 0`

You can't subtract as the first x has a degree (exponent) of 2 and the second x has a degree of 1.

However, for example:

`3x^(4) -1x^(4)=0`

You can subtract this to be
`2x^(4)` as both variables have a degree of 4.
