Find the constant k so that : -x2 - (k + 10)x - 8 = -(x - 2)(x - 4) Select the correct option.
A) 11	B) 12	C) 16	D) 14	E) 15
-x2 - (k + 10)x - 8 = -(x - 2)(x - 4) : given   -x2 - (k + 10)x - 8 = -x2 + 6x - 8   -(k + 10) = 6 : two polynomials are equal if their corresponding coefficients are equal.   k = -16 : solve the above for k   correct answer 16
