A "like term" for h² shares the same variable and exponent with h². Since h² has a single variable (h) raised to the power of 2, any term with the variable h raised to the power of 2 is a like term.
In algebra, like terms refer to terms that share the same variable and the same exponent on that variable. They can differ only in their coefficients, which are the numerical factors multiplying the variables.
Therefore, like terms for h² include:
4h²
-3h²
5h²
xh² (where x represents any constant number)
However, terms like:
h³ (different exponent)
2h (different power)
3x² (different variable)
1 (constant, no variable) are not considered like terms for h².
