Find the constant k so that : -x2 - (k + 8)x - 8 = -(x - 2)(x - 4)  Select.
A) 11  B) 12  C) 14  D) 19  E) 15
-x2 - (k + 8)x - 8 = -(x - 2)(x - 4) : given   -x2 - (k + 8)x - 8 = -x2 + 6x - 8   -(k + 8) = 6 : two polynomials are equal if their corresponding coefficients are equal.   k = -14 : solve the above for k   correct answer 14
