Question

which of the following polynomials is in standard form?y^12-y^15+y^10-4yz^5+z^3-z^2-42z^3+z^5-9x+x^2+x^3+x^4

Answer 1

For a polynomial to be in standard form, the terms are arranged from the highest exponent to the lowest exponent.

Thus, from the polynomials given, the polynomial in standard form is:

`z^5+z^3-z^2-4`

This is because the term with the highest exponent is the first term, the next exponent is 3, followed by the term with an exponent of 2, then the last term is the term with the least exponent.

ANSWER:

`z^5+z^3-z^2-4`
