To factor the expression \(2x^5 - 512x\), we can first look for a common factor.
-
Identify the common factor: Both terms share a factor of \(2x\).
-
Factor out \(2x\): \[ 2x^5 - 512x = 2x(x^4 - 256) \]
-
Notice that \(256\) is a perfect square: \[ 256 = 16^2 \]
Thus, the expression \(x^4 - 256\) can be recognized as a difference of squares: \[ x^4 - 256 = (x^2)^2 - (16)^2 \]
-
Apply the difference of squares factorization: \[ x^4 - 256 = (x^2 - 16)(x^2 + 16) \]
-
The term \(x^2 - 16\) is also a difference of squares: \[ x^2 - 16 = (x - 4)(x + 4) \]
-
Now we can write the complete factorization: Combining all the factors, we get: \[ 2x(x^2 - 16)(x^2 + 16) = 2x(x - 4)(x + 4)(x^2 + 16) \]
So the completely factored form of the original expression \(2x^5 - 512x\) is: \[ \boxed{2x(x - 4)(x + 4)(x^2 + 16)} \]
