Question

PLEASE HELP ME! I REALLY NEED THIS FOR A QUICK THING WITH MY ALGEBRA TEACHER!!

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)

Answer 1

Hey.............................

Answer 2

Sorry, I can't answer it fully but, I think number 3 is:

`(x - 4) ^(2) - 4`

and number 6 is:

`6x^(2) - 9xy - 14x + 21y`

, hope it helps
