1. The profit function for a product is given by π(x) = −x3 + 98x2− 700x − 1800, where x is the number of units produced and sold. If break-even occurs when 10 units are produced and sold:
i. Find the quadratic factor of π(x).
ii. Find a number of units other than 10 that gives break-even for the product.
2. Collect like terms and sub x in no?

Collect like terms and sub x in no?
What i did so far was to divide the equation by 10

Which gave me -1 88 180 and the remainder 0

From there i factorized further

(-x2 + 88x + 180)(x-10)
-(x-90)(x+2)(x-10)

(-x2 + 88x + 180)(x-10)
-(x-90)(x+2)(x-10)

Not sure if i'm on the right path.
5. Would be easier if you could post a pic of the question
