Given the binomials (x - 3), (x - 1), (x + 2), and (x + 3), which one is a factor of f(x) = 2x3 + 3x2 - 2x - 3?
spayn [35]

Answer:

(x-1) is factor of our function.

Step-by-step explanation:

We are given a function f(x)=2x^{3} +3x^{2} -2x-3 and we are asked to find the correct factor from the given options.

Let us factor out our polynomial.

2x^{3} +3x^{2} -2x-3

x^{2} (2x+3)-1(2x+3)

(x^{2} -1)(2x+3)

(x+1)(x-1)(2x+3)

Therefore, (x-1) is correct choice for factor of our polynomial.

6 students share 5 small pizza needs to be share equally
dusya [7]
                             5 pizza / 6 student  =  'Z' pizza / 1 student

Cross-multiply the proportion:       

                             5 pizza-student  =  6 Z  pizza-student

Divide each side of the equation by 6 pizza-student :        

                             5/6  =  Z

Each student gets 5/6 of 1 pizza.

It's not so complicated.  Cut each pizza into 6 slices,
and each student gets 5 slices.

That's the same as  (83 and 1/3) percent of a pizza.
