24 in 6 months is 48 in 12 months
He read 4 books a month so 44 books in 11 months
So theyre trying to scare you in this question by giving you the zeros to an already existing function. Basically if x = 1, than the reverse function of this is (x-1)
using that, we can say that the zero or "root" "-2" is equal to (x+2)same with 3, we can say (x-3)= x = 3 and with five, (x-5)= x = 5
so, we have those functions, we can multiply them to eachother to work backwards.(x+2)(x-3)(x-5) =(x^2-x-9)(x-5) =x^3 - 6x^2 - 4x + 45
please ask if you have questions
So here we just are gonna distribute and simplify.
Answer:
2x²+5x-6 = 0
using the quadratic formula
x = 0.886 and x= -3.386
