Answer 1

1) Enter the missing numeral of the answer 1, 3. Use a number only.
2) f(x) = x^2 - 5x - 6 can be written as f(x) = x^2 - 5x - 6 = (x-1) (x+6)
the zeros are 1 and 6, and the smallest zero is 1,
3) g(x) = x^2 - 8x =g(x) = x(x - 8), so the zeros are 0 and 8, the smallest zero is 0
4) f(x) = x^2 - 7x + 6 can be written as f(x) = x^2 - 7x + 6 = (x-1) (x-6), the zeros are 1 and -6, and the smallest zero is 1
5) g(x) = x^2- 6x - 16 can be written as g(x) = x^2- 6x - 16 = (x+2) (x-8)
the zeros are -2 and 8, the smallest zero is -2
