2.

Reorganize this polyexpression so it is in "standard form". This means
The monomial with the highest degree should come first, with every next monomial of equal or lesser degree.
Whenever possible, order the variable factors within a monomial alphabetically.
9x^{2}+x^{4}+128+12x-5x^{3}

5.

Simplify the expression. Make sure your answer is in standard form for a polynomial.
(14p^{4} + 11p^{2} – 9p^{5}) - (-14+ 5p^{5} - 11p^2)

1.

Select all (and only) monomials of degree 7.
HINT: Make sure that the sum of all exponents of variables in the term is 7. But also make sure the term is actually a monomial!

8(ab)^{4}c^{1}

13q^{9}j^{-2}

7x^{4}

4x^{2}y^{3}z^{2}

9t^{7}

3.

Choose the option that meets all three requirements:
The expression is equivalent to (-9t^{2}-8v)+(-2tv-2v^{2}+t^{2})+(-v^{2}+4tv)
The expression is in standard form
All like terms have been combined

-11t^{2}+2tv-v^{2}

-8t^{2}-3v^{3}+2tv-8v

-8v^{2}-3t^{3}+2vt-8v

-11t^{2}-v^{2}+2tv
