If a polynomial function f(x) has roots -9 and 7 - i, what must be a factor of f(x)? (x-(7+ i))
(x - (-7-i)
(x + (7 + i))
(x + (7-i))

the answer is (-4,-4)

hope this ! : d

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
