You may want a 2nd opinion. Here is what I get:
Lim x—>0 +++%28f%28x%29%2F%28Ax%5E4%2BBx%5E3%29%29+=+C+ A,B,C constants
Lim x—>0 ++%28f%28x%29%2Fx%5E2%29+%2A+%281%2F%28Ax%5E2%2BBx%29%29+ = C
Lim x—>0 ++%28f%28x%29%2Fx%5E2%29+ * Lim x—>0 ++%281%2F%28Ax%5E2%2BBx%29%29+ = C
Lim x—>0 ++%28f%28x%29%2Fx%5E2%29+ = C / ( Lim x—>0 ++%281%2F%28Ax%5E2%2BBx%29%29+ )
The RHS denominator goes off to infinity, so C/denominator —> 0
Lim x—>0 +highlight%28++%28f%28x%29%2Fx%5E2%29++=+0+%29++
