Find the constant k so that : -x2 - (k + 11)x - 8 = -(x - 2)(x - 4)  Answers:
A) 11
B) 12
C) 17
D) 14
E) 15

Rationale: "- x 2 - ( k + 11 ) x - 8 = - ( x - 2 ) ( x - 4 ) : given - x 2 - ( k + 11 ) x - 8 = - x 2 + 6 x - 8 - ( k + 11 ) = 6 : two polynomials are equal if their corresponding coefficients are equal . k = - 17 : solve the above for k correct answer c"
Answer: C
