[RESOLVED] Break-even quadratic equation

[K-PRO]

Hey everybody

I have a problem that I am facing trouble solving regarding break-even

I got the total cost and the revenue functions below where x represents the number of production units and I need to find the number of units to make in order to break even

C(x) = 6300 + 80x + x^2
R(x) = 240x

My solution:

B.E(x) = 240x = 6300 + 80x + x^2
x^2 - 232x + 6300 = 0

Now I am supposed to find x, i tried by factoring but I never really found a solution with no fractions. Tried the quadratic formula didnt work either and i got different answers. I used an online quadratic equation calculator and it gave me different set of answers.

Now i am totally confused and frustrated as I am trying to find a solution, help would be appreciated

thanks in advance

You subtracted by 8 instead of 80.


I'd help with the rest but you seem to know how it's done from there.
