Simplify. (If it is already in simplest form, enter the given expression.)

−54a^2 − 84a/(all over)
18a^3 + 28a^2

−54a^2 − 84a/18a^3 + 28a^2

My result was first 3/a or -3(9a-14)/a(9a+14) but I got it wrong anybody able to help thank you!

$$\frac{ -54a^2-84a }{ 18a^3+28a^2 }$$

anonymous · Answer

factor out the a on the top and bottom, also factor out atleast a 2 from the top and bottom, then try another 2,
