Hi,

I've a question on my assignment paper I just want to check to make sure I'm doing it right.

Q: Factorise the numerator and denominator of each of the following and then cancel out any common factors:

x(squared) + 2x - 3

-------------------

x(squared) + 5x + 6

So what I did was get the factors of both equations -

x(squared) + 2x - 3

factors are (x-1)(x+3)

x(squared) + 5x +6

factors are (x+2)(x+3)

so:

(x-1)(x+3)

-----------

(x+2)(x+3)

x(-1+3)

---------

x(2+3)

cancel the x's.

-1+3

------

2+3

= 2

---

5

Is that correct?
