Use Quadratic Formula
or this one can be factored: you need 2 numbers whose product is -3 and when these are combined with the factors of 6 add up to -7
3 * -3 = -9 2 * 2 = 2 -9 + 2 = -7
SORRY - the second line should read 2 * 1 = 2
but the answers that are in th ebook are completly diff than what i would get if i factored?

the answer is {-1/3, 3/2}
so the factors are (3x + 1)(2x - 3) = 0 3x + 1 = 0 or 2x - 3 = 0 so x = -1/3 or x = 3/2 yes
how did you get those factors
im conf
in my second post i was wotking out the factors
