Are there any questions in particular you'd like to discuss? Surely you can't be stuck on all of them!
I have to take a placement test for my college orientation, and i have no problem with the highschool level math, but the college level looks rediculous.
if i post the link then maybe someone could explain how to do it? its really short, not a lot of problems. and the answers are given lol i just cant get to them. Thanks.

For # 3 whenever you have an expression in the form.. ..you can multiply diagonally and the following is true..
So we have:..
Cross multiply:..
Solve for . You should get 2 for .
Now for # 7 are you familiar with the factoring method for quadratics?
Whenver you have an expression in the form.. .. you look for 2 numbers that multiply to get you and add up to .
So our quadratic is:..
Since a is 1, we always start with this: (x\,+\;\" alt="(x\,+\;\(x\,+\;\" />
But since c is negative, we now have: (x\,-\;\" alt="(x\,+\;\(x\,-\;\" />
We know
Also
Plus
We need the two multiples to add up to 1. These are and .
So the factored form is:..
