## anonymous 5 years ago 3x^2 – 5x – 2 Factor problem and show the work.

1. anonymous

you'll have to use delta and all that stuff

2. anonymous

$\Delta= b^2 - 4ac$ a=3 b= -5 c = -2 $\Delta = (-5)^2 - 4(3)(-2) = 49$ so : $x = -b \pm \sqrt{\Delta}/2a$ substitute delta and do the calculation :) give it a try.

Your answer should be:$x1 = 2$ and $x2 = -1/3$ did you get that?

nice sstarica you are smart

6. anonymous

thank you ^_^

If the directions said to factor, then you can't use the quadtratic formula. The answer would be (3x + 1)(x - 2) there is no solution if you don't have an = sign to begin with.

u also can use the calculator ..its very easy and efficient..

but you've got to learn the way too :) never trust techonology in the end, they fail you.
