Question

(x+1)/(x^2+6x+5)=(x+2)/(x^2+7x+10) I've checked it and Im pretty sure its all real numbers. But are there any exclusions?

Answer 1

x should not be equal to -1,-5,-2
because when you put it in to equation you get infinity = infinity
so we need to exclude -1,-5,-2

Answer 2

bingo

Answer 3

yeah
