(n^4 - 1) = (n^2 - 1) (n^2 +1) = (n - 1) (n + 1) (n^2 + 1)
Ok so easy peasy
remember that when divide or multiply by negative, reverse the inequality symbol example
2>3 times -1=
-2<-3 so
-150x<u>></u>-2400
divide both sides by -150
flip sign
<u />x<u><</u>16
-336<u>></u>-21y
divide both sides by -21
flip sign
16<u><</u>y
they seem to have the same solution
x=y<u>></u>16
