kittiwitti1 · Answer

ok... I think I get it now...

kittiwitti1 · Answer

no... I got the second one wrong still @hartnn sorry http://prntscr.com/aaipol

astrophysics · Answer

It asks you factor it completely so you need to use sum of squares and difference of squares

astrophysics · Answer

$$(x+i 5)(x- i 5)(x+5)(x-5)$$

astrophysics · Answer

Actually your answer doesn't look right it should be $$(x^2+25)^2 $$ yeah?

kittiwitti1 · Answer

really? o: @Astrophysics

astrophysics · Answer

Yes, lets confirm: http://www.wolframalpha.com/input/?i=factor+x%5E4%2B50x%5E2%2B625

kittiwitti1 · Answer

No... it is still wrong :-( http://prntscr.com/aax21g

kittiwitti1 · Answer

This method is also wrong T ^ T http://prntscr.com/aax2vg

astrophysics · Answer

$$(x^2+25)^2 \neq (x+5)(x-5)(x-5 i ) (x+5 i )$$

astrophysics · Answer

It's sum of squares twice

kittiwitti1 · Answer
