Me! i really need this for a quick thing with my algebra

3) complete the square and write the following in vertex form.
x2 - 8x + 12

4) determine the factors
x2y + 3x2 + 3y + 9

5)
write a polynomial that is a difference of two squares and describe how to factor it completely. identify the zeros of the equation and the x-intercepts.

6) write the polynomial that these are the factors for. (hint: multiply the factors)
(3x - 7)(2x - 3y)

30 points! here is a you are the new manager at trusty goods wholesale produce. you need to figure out how to adjust the amount of produce in your notes after the events of the day: you got 5 more crates of bananas someone returned 2 crates of apples a worker dropped a crate of grapes (oh no! , you had to throw them out) you sold a crate of bananas you sold 5 crates of apples can you write an expression to describe your day using: "a" for crates of apples "b" for crates of bananas and "g" for crates of grapes? make sure the expression is in simplest form question 2 (3 points) explain your steps using sentences.
