so i found the interval of width of 0.025 to be 1.35 and 1.375 however the answer has an inequality in it.

Can someone help please?

Website is down but I'm assuming it's asking for a root within an interval, which makes sense because 1.35<\alpha <1.375 is the interval within which the equation equals 0 or whatever it's asking for.

Then I was right. f(\alpha)=0 therefore we are looking for x=\alpha between x=1.3 and x=1.4
...or to put it differently; 1.3<\alpha<1.4

You are bisecting this interval until its width is 0.025 which is where you got 1.35 and 1.375 from.
Hence \alpha lies between these to values. Or to put it differently; 1.35<\alpha<1.375
