solving_quadratics_by_factoring/original/125 #161559

Question is: Solve factorable quadratic equations (leading coefficient is 1). Solve quadratic equations of the form x^2+bx+c=0 that can be rewritten according to their linear factors. Solve for x:

x^2 - 11x + 10 = 0

Shouldn't the answer be -10 and -1 ? Since the "2nd" coefficient is -11?
