Ответ:
121x² + 36y²
Explanation:The question is equivalent to, "which answer cannot be factored anymore?"
This is the sum of squares (11x)² +(6y)². Such a sum has no factorization in real numbers.The first factor can have a factor of 4 removed: (4x+4) = 4(x+1)The difference of squares can be factored: (x²-4) = (x-2)(x+2)Each term has a coefficient that is a multiple of 3, so 3 can be factored out.Ответ:
