The profit function for a product is given by P(x)=-x^3+9x^2+100x-500, where x is the number of units produced and sold and P is in hundreds of dollars. Use factoring by grouping to find the numbers of units that will give a profit of $40,000. The number of units that will give a profit of $40,000 are . (Type an integer or a fraction. Use a comma to separate answers as needed.)

8y^50

step-by-step explanation:

no not all of them.

step-by-step explanation:

some of them have a square base.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
