pleez help factor!
6x(squared)-20x-16
any ideas?
2006-12-14 09:15:12 · 7 answers · asked by Anonymous in Science & Mathematics ➔ Mathematics
(2x-8) (3x+2)
why?
i looked for factors of 6 and -16
6 = (2) (3) (first term of two binomials)
-16= (-8) (2) (second terms of binomials)
there are a lot of factors but why i chose these?
we have to consider middle term which is -20...
middle term is the sum of the product of inner terms and outer terms...
inner terms are -3x and 8
outer terms are 2x and 2
(-3x)(8) + (2x)(2) = -24x+4x= -20x (middle term)
hope that this will help you...

2 * (3x - 4) (x + 2)
you gotta factor out the 2 first, then do the work
...i love how every one got a different answer
