Question

The
factors of (×-y) -4(×-y)-45 is​

Answer 1

Answer:

the only possible answers are y = 1 or y = 3

Explanation:

x^2y^2 and xy^3 have a common factor of xy^2

If x and y are positive integers any common factor of x^2y^2 and xy^3 must itself have a factor of y^2

If 45 is the greatest common factor (or any factor) of x^2y^2 and xy^3

then 45 must contain y^2 as a factor.

Restricting ourselves to positive factors:

XXX

45 = 12 × 32 × 5

So y must be either 1 or 3

Answer 2

Step-by-step explanation:

let (x-y)=a

now we will solve this quadratic equation
