3x^2 – 5x – 2 Factor problem and show the work.

Question

anonymous · Answer

you'll have to use delta and all that stuff

anonymous · Answer

$$\Delta= b^2 - 4ac$$

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.

what will your answer be?

anonymous · Answer

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

anonymous · Answer

nice
 sstarica you are smart

anonymous · Answer

thank you ^_^

anonymous · Answer

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.

anonymous · Answer

but you've got to learn the way too :)
