Answer:
9 and 5.
Step-by-step explanation:
So we have the expression:
In order to combine like terms, the variables must be <em>exactly</em> the same: not one less, not one more.
3x²y and 2x² <em>cannot</em> be combined because the first value has a y.
7x², 3x²y, and 2x² also <em>cannot </em>be combined because the second value has a y.
9 and 5 is the only one that can be combined because they are just integers. They can be added to be 14.
2, 3, 5, and 9 <em>cannot</em> be combined because the 2 and the 3 are tied to the variables as coefficients. They are not constants.
