Q. x3x3+9x2Which expression is equivalent to the given expression for all x>1 ?Choose 1 answer:(A) 9x2(B) 1+9x2(C) xx+9(D) x1+9x
Simplify Expression: Simplify the given expression by dividing each term in the numerator by the term in the denominator.The expression is (x3+9x2)/(x3). We can divide each term in the numerator by x3 separately.
Divide Terms: Divide x3 by x3 and 9x2 by x3. x3/x3=1 (since any non-zero number divided by itself is 1) 9x2/x3=9/x (since when dividing powers with the same base, we subtract the exponents: 2−3=−1)
Combine Results: Combine the results from Step 2.The simplified expression is 1+x9.
Match Answer Choices: Match the simplified expression with the given answer choices.The simplified expression 1+x9 corresponds to answer choice (D) (1+9x)/(x).
