This is actually a tricky question

Given that x<0

Quantity A: \(x^2-x^5 = x^2(1-x^3)\) now \(x^2\) is always positve as \(x \neq 0\) but \(1-x^3\) may or maynot be positive.

If \(|x| > 0\) then \(1-x^3\) is negative.

Try plugging values: \(x=-0.5\)

Quanity A: 0.21875 here quantity A is greater.


\(x=-1.5\)

Quanity A: -5.34375 here quantity B is greater.


Hence the correct option is D.

Hi Sandy, if the correct answer is D, can you please update the Reveal Answer to D? It is still A.
