Question 2

2.

Reorganize this polynomial expression so it is in "standard form". This means
The monomial term with the highest degree should come first, with every next term of equal or lesser degree.
Whenever possible, order the variable factors within a monomial alphabetically.
34a+2b^{2}-19+3a^{5}b

Question 1

1.

Select all (and only) the trinomials of degree 3.

HINT: Make sure that the greatest sum of all exponents of variables in any term is 3. But also make sure the polynomial has 3 terms.

438p^{2}q-75pq+20q-80

-8r^{2}s+27

3xy^{2}z+9yz^{3}

2x^{2}-9x+1

h^{3}-6h-2

Question 3

3.

Choose the option that results when you combine all like terms and express the result in standard form.

(9s+t^{2})-(18s^{2}+3)+(3t^{2}-5s+11)

-18s^{2}+4t^{2}+4s+8

-18s^{2}+3t^{2}+t^{2}+9s+-5s+-3+11

9s+t^{2}+-18s^{2}+-3+3t^{2}+-5s+11

8+4s+4t^{2}-18s^{2}

Question 4

4.

Simplify the expression. Make sure your answer is in standard form for a polynomial.

(g^{2}+5g^{3})-(3g^{3}-4g)

Question 5

5.

Simplify the expression. Make sure your answer is in standard form for a polynomial.

(\frac{1}{2}x^{2}+\frac{17}{16}x-\frac{9}{10})-\frac{1}{2}(x^{2}+7x-3)
