If u times x is equal to x to the 5th power minus x to the 4th power plus x squared and v times x is equal to negative x squared , which expression is equivalent to open paren u over v close paren times x ?
Answer
A
negative x cubed plus x squared minus 1
B
negative x cubed plus x squared
C
x cubed minus x squared
Explanation
Divide u(x) by v(x): (x⁵ − x⁴ + x²)/(−x²). Dividing each term by −x² gives −x³ + x² − 1, which is choice A, “negative x cubed plus x squared minus 1.”
