Question

Is my answer right?

Simplify:

3x^2 + 21x - 54
________________
x^2 + 3x - 54


= 10?

Answer 1

how do you get it? mine is not

Answer 2

I'm wrong:(

Answer 3

Unless they give you a value of X, the intent of this problem is to get you to factor both equations, not to find a number at the end.

Answer 4

sorry, wrong copy. the right one is

Answer 5

\[3+\frac{ 12x+108 }{ x^2+3x-54 }\]

Answer 6

This factors past the equation given above. Factoring x^2+3x-54 gives us (x - 6) (x + 9).
12x+108 is 12(x+9) so this can factor to \[3+\frac{ 12 }{ x+6 }\]

Answer 7

perfect! good combination
