URGENT Help ! ! Deion was asked to completely factor the expression 10x^4−160. Deion's answer was the following:

10(x^4−16)

10(x^2+4) (x^2−4)

Has Deion completely factored the expression? If yes, explain how you know. If not, explain what step Deion missed and what the correct solution would be.
