Question

Select one of the factors of x3y2 + 8xy2 + 5x2 + 40.

a) (xy2 + 5)
b) (x2 + 4)
c) (xy2 − 5)
d) (x2 − 8)

Answer 1

A) (xy^2+5)

Explanation:

The first guy was correct and I did the math and got the right answer on the exam and the same answer as the guy above

Answer 2

Option a -
`xy^2+5`

Explanation:

Given : Polynomial
`x^3y^2+8xy^2+5x^2+40`

To find : Select one of the factors of polynomial ?

Solution :

The polynomial
`x^3y^2+8xy^2+5x^2+40`

We factor of above polynomial by taking common terms,

`xy^2(x^2+8)+5(x^2+8)`

`(xy^2+5)(x^2+8)`

From the given options,

`xy^2+5` is one of the factors of polynomial.

Therefore, option a is correct.
