it has been over 5 years since i last took algebra and this stuff is dormant in my head. i know it's simple, but i can't remember it and the book is too advanced and doesn't explain it.

how do i factor the following:

6x²+7x-3=0

from what i can remember..... i know it has to go like this
(x__+___)(x__+___)

and that one side is the sum of 2 integers, and the other is the product of 2 integers... but i can't remember the order....
can you please help?

When rounding to preserve significant figures, why is it that when the digit removed is 5, the preceding number is increased by 1 if it is odd and remains unchanged if it is even? For example, what is the logic in rounding 17.71 to 17.8, but 17.79 to 17.7? Clearly, that is unreasonable!

I know that you DO, what I'm asking for is a justification. We're always taught that when you have to divide fractions, you just multiply by the reciprocal, but I've never understood why this is so. Thanks for your help.

So I had to find four least common multiples done out below:
a) LCM(8,12) = 24
b) LCM(20, 30) = 60
c) LCM(51, 68) = 204
d) LCM(23, 18) = 414

For each of the LCMs computed above, I have to compare the value of LCM(a, b) to the values of a, b, and gcd(a,b) and find a relationship between the two.

So I've basically calculated the gcds and retrieved the following:
a) gcd(8,12) = 4
b) gcd(20,30) = 10
c) gcd(51,68) = 17
d) gcd(23, 18) = 1

The only relationship I've found is that the difference between a and b is the gcd for them in cases a through c. I was wondering, is there another pattern I should be aware of here?

I'm solving for both b and a
started with:
90+b+a=180
so:
b=90-a
so I substitute it in the original solution:
90+(90-a)+a=180
which goes to
(90-a)+a=90
that's where I get stuck

I can't remember how to keep going to solve for 'a' (it's been a couple years since my last math class)
you don't have to solve it out in the answer, but if you could just tell me what to do. I've been stuck on this for over an hour.
Thanks in advance
