If f(x)=x^3-4x^2-37x+40f(x)=x 3 −4x 2 −37x+40 and f(8)=0f(8)=0, then find all of the zeros of f(x)f(x) algebraically.

Given:

The function is:

To find:

The all of the zeros of f(x) algebraically.

Solution:

We have, is means 8 is a zero of given function and (x-8) is a factor of given function.

The function is:

Spittle the middle terms in such a way so that we get (x-8) as a common factor.

Spittle the middle term of the quadratic expression, we get

For zeros, .

Therefore, the all zeros of the given function are -5, 1 and 8.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

41*67/2=1373.5
