x^2=-11x-10 ?

  • math -

    Where did you get 110 from exactly?

  • math -

    Good question. I don' see no steenking 110.

    However, if you want to solve the equation above, collect everything to one side:

    x^2 + 11x + 10 = 0
    (x+1)(x+10) = 0

    so, if x = -1 or x = -10, the equation is satisfied.

    check:

    (-1)^2 =? -11(-1) - 10
    1 =? 11 - 10
    yes

    (-10)^2 =? -11(-10) - 10
    100 =? 110 - 10
    yes.

    Ah. Now I see a 110. It's 11*10
