59 is a tough bird to deal with; its only factors are 1 and 59.Therefore, forget about factoring. Instead, use the quadratic formula, or solve the equation by completing the square.Please note: x2 is ambiguous. Please, type x^2 to indicate "squared 2".Here you have 1x^2 - 12x + 59 = 0, for which a=1, b=-12 and c=59.The use of the quadratic formula: x=[-b plus or minus sqrt(b^2-4ac)] / (2a)to find the two roots. Note that the "discriminant" b^2 - 4ac is negative, meaning that its two roots will be "complex".
