hey everyone i hope ur all doing great! ok tomorrows my math final and i have a slight dilemma on the review sheet and i would appreciate it a lot if someone helped me with it!

here it is:

[tex]z^4+75=28z^2[/tex]

ok so i first brought the 75 to the other side which gave me:

[tex]z^4=28z^2-75[/tex]

and now im stuck! i dont know if i should go back and rewrite z^4 as [tex]z^2z^2[/tex] or what??

any help is appreciated!! thanks!!
