Question

Write a linear factorization of the function.

f(x) = x4 + 64x2

f(x) = x2(8x + i)(8x - i)

f(x) = x2(x + 8i)2

f(x) = x2(x + 8i)(x - 8i)

f(x) = x2(8x + i)2

Answer 1

factor the gcf

Answer 2

\(f(x) = x4 + 64x2\)

\(x^2(x^2+64)\)

Answer 3

sorry I was getting something to eat

Answer 4

um its x^2

Answer 5

ha its okay.. thats right, next factor \(x^2 + 64\)

Answer 6

right

Answer 7

\(x^2+64\)

\(x^2+8^2\)

\((x+8i)(x-8i)\)

Answer 8

ok

Answer 9

f(x) = x2(x + 8i)(x - 8i)
