Thanks.. it was just a typing error. it can not be solved. :)
You're not solving anything, since you haven't written an equation. I presume that your homework problem involves factoring the expression above. You probably learned some rules about separating common factors (like -1), and how to treat coefficients which are exact squares. Try applying those rules and see where you get.
X = (-16)-(9×2) = - 34 ____OR____ X = - (16+9)×2 = - 50 The Maker knows what '2 means, Factorial ? I take it as typing error.
