(-9x3+3x2-15x)/(-3x)
 
This is a fraction in the form (a + b + c)/d which = a/d + b/d + c/d
 
=  (-9x3/-3x) + (3x2/-3x) + (-15x/-3x)
=  (   3x2    ) + (    - x    ) + (     5     )
 
= 3x2 - x + 5

Comments

Answer is equivalent to original expression only if x ≠ 0. Try putting 0 in for x in both expressions.
