    2(2x+11x)=-22 2\2(2x+11x)=-22/2 2x+11x=-11 12x/12=-11/12 x=-11/12

    No, it's not (x-11)(x-2) FOIL it and it doesn't come out the same

    so the factor is by grouding (x^2+11x)+25 then you x(x+11)+25 that is your answer

    x^2+11x+22=0 x= [-11+(121-88)^1/2]/2=[-11+(33)^1/2]/2 and one more root is [-11-(33)^1/2]/2
