simplify: 3x^2 + 21x - 54/x^2 + 3x - 54

Question

anonymous · Answer

To simplify you must combine like terms.

$$3x ^{2} + 21x - 54x ^{2} +3x -54$$

You can combine everything that is alike so...

$$3x^2-54x^2 = -51x^2$$

$$21x + 3x = 24x$$

And nothing can combine with -54 because it has nothing alike it in the equation.
So then you just put them together which becomes $$-51x^2+24x-54$$.

Does that make sense?

Since you started with an x^2 and a x and number you should end with the same unless something subtracts from the other.  My answer above is the answer you should get.  Do I need explain more?

No I just had to go through it again on my own paper. Thank you for your help.
