Write the rational expression in simplest form and get the restrictions.

Question

(-10x - x) / (x^2 +12x+20)

Answer 1

Your turn,
show me what you got so far

Answer 2

= -(x+10)/( x^2 +10x +2x +20)
=-(x+10)/x*(x+10) + 2*(x+10)
=-(x+10)/(x+10)(x+2)
the two (x+10) get cancelled and then the top will be -1 and the bottom is (x+2): -1/(x+2). now how do i get the restriction
