Look...you have given two roots...so form a quadratic equations from them...[X-(-2)][X-(-1)]
Okk...so solving this...you will get a equation....this will be a factor of given equation....so now divide the given equation by the equation obtained...by further solving the quotient obtained from division...you will get other two roots..
