    w = width of border (14 + w)(18 + w) = 480 252 + 32w + w^2 = 480 w^2 + 32w - 228 = 0 ( w + 38)(w - 6) = 0 so w = -38 (impossible) or w = 6 6 in

    x²+6x+3=0 x² +6x +9 +3 =9 (Add the square of 1/2 the coefficient of x to both sides.) x²+6x +9 = 6 (Simplify) (x+3)²=6 (Write the trinomial as a perfect square. x+3 = ±√6 (Take the square root of both sides.) x=-3 ±√6 (Simplify) I choose completing the square because it requires less arithmetic than the other common method of using the quadratic formula. Graphing would not produce an accurate answer and since it cannot be factored into whole numbers, that method is not desirable.
