Which of these numbers is greater than 2.25 but less than 1? Is it 1 or 1.5 or 0 or 2.5 I think the answer is 1.5 but can someone tell me how I came up with this answer. He has to write it down.

the answer is 1.5 of course because converting them into their fractional form indeed informs u that 1.5 is the solely answer

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
