Can I get some help solving this, I already tried the answers (x+3)²(x²-10x+29) and (x+3)(x+3)(x²-10x+29) but it keeps saying it's wrong.

Use division to show that the indicated polynomial is a factor of the given polynomial function f. (x + 3)2; f(x) = x4 - 4x3 - 22x2 + 84x + 261 Yes, the indicated polynomial is a factor of the given polynomial function. O No, the indicated polynomial is not a factor of the given polynomial function. Find all other zeros. (If there are no other zeros, enter NA. Enter your answers as a comma-sep X = 5 + 2i, 5 - 2i Give the complete factorization of f(x). f ( x) = (x+ 3) (x+ 3) (x2 - 10x +29 x
