Question

how do i simplify this??

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

Answer 1

do i factor?

Answer 2

yes..factoize both num and denom.

Answer 3

factorize*

Answer 4

Yes, then perhaps they will have a common factor which you can cancel out.

Answer 5

Numerator:
x^2 + x + 2x + 2
= (x + 1)(x + 2)
Denominator:
x^2 - x - 2
= x^2 + x - 2x - 2
= (x + 1)(x - 2)

Answer 6

so uhh some hints on how to factor this? :)

Answer 7

I just did that.

Answer 8

oh

Answer 9

so x+1 gets canceled?

Answer 10

That's riht, you'll be left with (x + 2)/(x - 2).

Answer 11

ohhhh

Answer 12

in ques it should be mentioned x not equal to -1 though..

Answer 13

x = -1 will give denominator as 0.

Answer 14

uhmm could tisalso be simplfied by dividing?

Answer 15

I'm not sure ... I don't think so.

Answer 16

oh hmm
