Halppp pls... :(

$The\ solutions\ to\ the\ equation\\ 6x^2 + 10x = 4 - 10x - 6x^2\\ can\ be\ written\ in\ the\ form\ x=\frac{P\pm \sqrt Q}{R},\\ where\ P \ and\ R\ are\ relatively\\ prime\ integers\ and\ R>0. \\ What\ is\ the\ product\ PQR ?$ 

 Also on the web already, the answer is wrong, and I want a nudge.... Not all of the Answer...
