What is obtained by simplifying (\frac{x^5+3x^2}{x^2}) for (x\neq0)?

Answer and explanation

Correct answer: (x^3+3)

The direct answer is A, x³+3. Because x≠0, cancellation by x² is allowed. Work term by term: x⁵/x²=x^(5−2)=x³, and 3x²/x²=3x^(2−2)=3. Therefore the whole expression becomes x³+3. Option A matches this calculation. Option B incorrectly keeps the original fifth power and also loses the effect of dividing both terms by x². Option C incorrectly leaves 3x² unchanged, although x² cancels completely from that term. Option D incorrectly reduces x⁵/x² to x² instead of x³ and therefore gives the wrong result. The condition x≠0 matters because division by x² and cancellation are not valid at x=0. The result is a polynomial in the simplified form, with degree 3 and constant term 3. Memory trick: when dividing powers with the same non-zero base, subtract exponents.
