I can’t see those image files. Could you either paste the expressions here or re-upload the images? Once I can read them I’ll show which choice is equivalent and explain why.
If it helps, here are two quick ways you can check equivalence yourself before sending the images:
1) Algebraic simplification
- Factor numerators/denominators, expand if needed, cancel common factors, use exponent rules, or apply identities (difference of squares, perfect-square trinomial, etc.).
- Example: (x^2 − 4)/(x − 2) = ((x − 2)(x + 2))/(x − 2) = x + 2 (for x ≠ 2).
2) Numerical testing
- Pick several values of the variable (avoid values that make denominators 0) and evaluate each expression. If the results match for enough distinct values (3 or more), the expressions are almost certainly equivalent.
- Example: test x = 0, 1, 3 for two expressions.
Paste the choices and the original expression and I’ll work it out step‑by‑step.
