The profit for a product is given by P(x)=-11xsquared+1430x-39,600 where x is the number of units produced and sold. How many units give break even (that is, give zero profit) for this product?
Answer provided by our tutors
P(x)=-11x^2+1430x-39,600
We need to find 'x' such that P(x) = 0, that is:
-11x^2+1430x-39,600 = 0
