## anonymous one year ago The Quadratic Formula gives which roots for the equation 2x^2+x-6 ?

1) That is not an equation. 2) If you add "=0", then that is a true statement. Why do you demonstrate it?

2. anonymous

ohh i forgot to add the =0

Okay, and now for #2? You demonstrate the Quadratic Formula.

5. anonymous

me?

6. anonymous

i don't know thats why i asked tho

7. tkhunny

That makes no sense. Why would you post a problem statement suggesting the "Quadratic Formula" if you've never seen it. You MUST have SOMETHING. Give us anything to go on.

8. anonymous

don't worry i changed the question

9. anonymous

thank you

I'm only worried about you learning. If you get others to do your work, or you show no work of your own, it is unlikely you will be learning. Do not post questions with no work shown.

X=-b(+-)(b^2-4ac)^1/2whole divided by 2a

You've never seen this? Given $$ax^{2} + bx + c = 0$$, solutions or x are given by $$x = \dfrac{-b\pm\sqrt{b^{2}-4ac}}{2a}$$. Just identify the three values and substitute.
