The vertical asymptotes for a rational expression, occur at the values of "x" that make the denominator 0, and therefore the expression undefined.
what are those anyway? simple, just set the denominator to 0, solve for "x", and that will spit them out.
x + 4 = 0
x = -4
there, if "x" ever becomes -4, then the fraction turns to
thus, that's where the vertical asymptote is at, x = -4.
