Hi,
My name is Kevin. I am 34 years old and I would like to enroll in College as a freshman. I'm studying to pass the placement test and Algebra is my weakest link. The school gives a sample test online with nine Algebra questions. At first I could only do one. Now I can do two or three. I would like to post two questions here that I can't figure out. I need to know what type of questions these are so that I can find more examples for practice and if you could break them down step by step that would be awesome.
1)
x^2 - x - 6
__________ =
x^2 - 4
(This is a fraction)
A.
x - 3
________
2
B.
x - 3
_______
x - 2
C.
x - 3
______
x + 2
D.
3
___
2
2)
(3x-2y)^2 =
A. 9x^2 - 4y^2
B. 9x^2 + 4y^2
C. 9x^2 + 4y^2 - 6xy
D. 9x^2 + 4y^2 - 12xy
Thank you
What do you mean by factorise the numerator and denominator and then simplify the fraction by cancelling out the common factor?
What does expand mean for (3x - 2y)^2 = (3x - 2y)(3x - 2y) = ....?
I'm trying to avoid taking remedial classes but I think might have to.
If you were told to factorise the following:
(a) x^2 - x - 6
(b) x^2 - 4
would you know what to do and how to do it?
(Do you know what the words 'numerator' and 'denominator' mean?)
Do you know that (3x - 2y)^2 means (3x - 2y)(3x - 2y)? If you were told to expand (3x - 2y)(3x - 2y) would you know what to do and how to do it?
"If you were told to factorise the following:

No, I would not.
"Do you know what the words 'numerator' and 'denominator' mean?"
Yes, I do.
"Do you know that (3x - 2y)^2 means (3x - 2y)(3x - 2y)?"
Yes
"If you were told to expand (3x - 2y)(3x - 2y) would you know what to do and how to do it?"
No
I started studying from the Khan Academy website. I need a lot of help and I should get it there.
Thank You
