[quote name='thekeybladewars']Yes, that'd be great. (not my first year of college, but I skipped all over math and screwed myself over)
Okay, lets start from here: -12 +/- Square root of 279 all over -18.[/quote]
279? I thought it was 252, but aight.
root 279 = root 9 * root 31
root 279 = 3 * root 31...and you're done.
root 252 = root 36 * root 7
root 252 = 6 * root 7...and you're done.
If you don't immediately notice 252 = 36*7, then it'd go like this:
root 252 = root 4 * root 63
root 252 = 2 * root 63
root 252 = 2 * root 9 * root 7
root 252 = 2 * 3 * root 7
root 252 = 6 * root 7.
