P(x) = x^4 - 9x^2 - 4x + 12
P(1) = 1^4 - 9(1)^2 - 4(1) + 12 = 1 - 9 - 4 + 12 = 0
x = 1 is a root.
By dividing the polynomial by x - 1, gives other roots as 3 and -2

Write a linear factorization of the function. f(x) = x4+ 9x2 f(x) = x2(x + 3i)(x - 3i) f(x) = x2(x + 3i)2 f(x) = x2(3x + i)(3x - i) f(x) = x2(3x + i)
