No Maria is wrong because if you look at placement value you would see 4 is in the one hundred thousands place.
Use the least common denominator (LCD) to write these fractions as equivalent fractions with like denominators, and then compare them two at a time
D none of the above is the answer
(a^3 - 2a + 5) - (4a^3 - 5a^2 + a - 2)
=a^3 - 2a + 5 - 4a^3 + 5a^2 - a + 2
= -3a^3 + 5a^2 - 3a + 7
