Welcome to Openstudy!! 

First you can divide the entire equation by 2.

aravindg · Answer

What do you get? :)

anonymous · Answer

8 I am new to math and really need this to impress my frinds

aravindg · Answer

Good. Can you divide the whole equation by 2?

anonymous · Answer

aravindg · Answer

:O How can you show?

anonymous · Answer

what?

aravindg · Answer

hw did u get 8?

anonymous · Answer

This is what you should have done. I am curious to know what you did to get 8?
Hahaa
well you first want to divide the whole equation by 2 like AracindG said
so
2x^2 divided by 2=x^2
then 14x divided by 2=+7x
and -60 divided by 2=-30
So the equation we now have is
$$x^2+7x-30=0$$

Why not?

anonymous · Answer

It's purplemath my math teacher used to send us there all the time. It's a math site that just helps you with equations and gives examples.

anonymous · Answer

$$x=\frac{ -b \pm \sqrt{b^2 -4ac} }{ 2a }$$

anonymous · Answer

A quadratic equation like the one you have looks like this
$$ax^2+bx+c=0$$

anonymous · Answer

So in you case
a=1
b=7
c=-30

anonymous · Answer

Never mind I found what I needed you can stop trying to help me
