**Steve**, Tuesday, November 13, 2012 at 2:18pmGood 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
