If we let x be the number then the expression is:

`{2x-3}/x^2`    the numerator is the first part which is 3 less than twice the number 

The denominator is the number squared.

Now substitute `x=-2` into the expression to get:

`{2(-2)-3}/{(-2)^2}`   simplify numerator

`={-4-3}/{(-2)^2}`   evaluate denominator

`={-4-3}/4`   simplify numerator


The final value of the expression is `-7/4` .
