Which of the following are like terms in 4x^2 and 9x^2?

Explanation:
Like terms are terms that have the same variable raised to the same power. Here, both terms are x^2, so they share the same variable part and are like terms. The coefficients 4 and 9 don’t affect this classification, and you could combine them as 4x^2 + 9x^2 = 13x^2. The other pairs don’t fit because one has different powers (x vs x^2), or uses different variables (xy and yz, or a and b), so they aren’t like terms.
