The graph of \(y=\frac{5x^2-9}{3x^2+5x+2}\) has vertical asymptotes at \(x = a\) and \(x = b\). Find \(a + b.\)
The formula for the vertical asymptote of a equation of the form \(ax + b/cx + d\) is \(x = -d/c\). For the horizontal asymptote, the formula is \(x = a/c\).
The denominator of the fraction can be expanded into \((3x + 2)(x + 1)\). I don't know what to do next.
