Why answer is wrong my book?
Sorry possible to know what’s the ans indicated?
H=-16, k=12;(x-2)(x-1)(x+6)
I think the answer is wrong. Cos like if h=-16 and k = 12. When subs it back it, the ans doesn’t tally
F(-2) = -67 which is not 2k(24)
F(1) = -19 which is not k (12)
F(1) = -19 which is not k (12)
Ok. Thanks for the help too
