225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

no one knows lol

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin
