Answer 1

\[4.25 = x+ \frac{ 1 }{ x }\]

Answer 2

Are you possibly learning the quadratic formula right now?

Answer 3

Because all of these questions involve the quadratic formula.

Answer 4

\[4.25x=x^2+1\] and then \[4.25x+x^2-1=0\]

Answer 5

No.
We can only use the formula when the question "SAYS" round off your answer.

Answer 6

There is pretty much no other way of working it out other than guess and check .

Answer 7

I can't use it as the question is not asking me to.

Answer 8

-1/4 and 4?
