Question

Can you help me solve this problem for the roots by using the quadratic formula? 
2(6 - x) = x(x + 5)

anonymous · Answer

I don't know how to use the quadratic formula..

anonymous · Answer

As well as I'd like.

anonymous · Answer

start with 
$$2(6 - x) = x(x + 5)$$
$$12-2x=x^2+5x$$
$$x^2+7x-12=0$$ then go form there

@diamondsparkles5892 do you have an answer?

anonymous · Answer

ok, here:

starting from where satellite left off,

x^2 + 7x - 12 = 0

which means that a = 1, b = 7, and c = -12

if you dont know the quadratic equation already, it's
|dw:1358397439146:dw|


so now just plug in the values.
|dw:1358397599665:dw|

and then simplify it.

|dw:1358397665084:dw|
