Find the LCD of the 3 terms: Consider the factors of each of the quadratics: (x+5)(x+7), (x+7)(x+2), (x+5)(x+2) LCD: (x+5)(x+7)(x+2) Each of the terms needs one of the binomial factors. [(x+2)(x-3)-(5x-2)(x+5)+(x-8)(x+7)] / [(x+5)(x+7)(x+2)] -(3x+13)(x+4) / [(x+5)(x+7)(x+2)] Simplify using the distributive property.
