I need help with the following problems.

1.) Factor: y + 1000y^4

2.) Use the general factoring strategy to help factor this polynomial:

x^3 + 2x^2 + 2x^3 - 6x -15 + 3x^2 + 5

3.) Use the general factoring strategy (and the zero product property) to help solve this equation:

x^2 - 20x = -x^2 - 9x - 5

4.) Some of these trinomials are factorable, some are prime. Factor those that can be factored:

A.] 6 + 5t - 6t^2

B.] 6 + 5t + 6t^2

C.] 6 - 5t + 6t^2

D.] 6 - 5t - 6t^2

5.)

Use factoring to identify the zero's of this polynomial: 3x^5 - 30x^3 + 27x

Any help in explaining how you do these problems is greatly appreciated! I missed the first couple days of class due to illness and came back swamped, and lost as far as what to do.

Thanks in advance!
