Explanation:
Like terms are terms that have the same variable(s) raised to the same power(s). In the given expression, we have the following terms:
1. 7x
2. 5x^2
3. 7y
4. -5yx
5. -9x^2
To identify the like terms, we need to compare the variables and their exponents. Let's compare each pair of terms:
a) 7x and -5yx
- These terms have the same variable x raised to the power of 1.
- Therefore, 7x and -5yx are like terms.
b) 5x^2 and -5yx
- These terms have the same variable x raised to the power of 2.
- Therefore, 5x^2 and -5yx are like terms.
c) 5x^2 and -9x^2
- These terms have the same variable x raised to the power of 2.
- Therefore, 5x^2 and -9x^2 are like terms.
d) 7x and 7y
- These terms have different variables (x and y) and different exponents.
- Therefore, 7x and 7y are not like terms.
Based on the above comparisons, the like terms in the expression are:
- 7x and -5yx (option a)
- 5x^2 and -5yx (option b)
- 5x^2 and -9x^2 (option c)
However, option d is incorrect because 7x and 7y are not like terms. Therefore, the correct answer is option c) 5x^2 and -9x^2.

- Therefore, 5x^2 and -9x^2 are like terms.
d) 7x and 7y

- Therefore, 7x and 7y are not like terms.
Based on the above comparisons, the like terms in the expression are:
- 7x and -5yx (option a)
- 5x^2 and -5yx (option b)
- 5x^2 and -9x^2 (option c)
However, option d is incorrect because 7x and 7y are not like terms. Therefore, the correct answer is option c) 5x^2 and -9x^2.
