Verified answer

Since b^2-4ac = (14)^+4(4360) = 17636 is not a perfect square, you cannot factor it into the product of two binomials with integer coefficients.

Using quadratic formula, I got

x^2 -14xy-4360y^2

= (x+59.4003012y)(x-73.4003012y)

That's kind of odd... because I don't think that there are two numbers that subtract to give you 14 and multiplies to give you 4360... the closest combination of numbers I can come up with are 73 and 59 and that yields 4307, so it would like (x+59y)(x-73y), you might want to double-check the question
