Which statement is true about the factorization of 30 x squared plus 40 x y plus 51 y squared ?

The coefficients 30, 40, and 51 have a greatest common factor of 1: no integer greater than 1 divides all three. Also, the terms do not share a variable factor, since the first has no y and the last has no x. Therefore, the greatest common factor of the polynomial is 1, as stated in choice B.
