Answer 1

1. f(x) = x^2 -6x + 9

Factor

(x - 3)(x - 3)
Zeros,
x - 3 = 0
x = 3

Answer 3

number 2

Answer 4

you there?

Answer 5

For Number 2, it is the second option. This is because in f(x) = 2x^5 - x^4 -2x^3 + 4x^2 + x - 2 there are three changes in signs (positive and negative) with this being the positive case (as per f(x) ). Therefore we know that there are three or one positive zeroes.
