1 / 2y - 4
BTW, generally you say 2y rather than y2.
The expression Y-2 is 1/Y2. The reciprocal of 1/Y2 is Y2.
In math a reciprocal is the number you multiply a given number by to get 1. The easiest way is to put the given number under 1 in a fraction as the denominator. Hence the reciprocal of 4 is 1/4 or 0.25, the recprocal of (x2+2xy+y2) is 1/(x2+2xy+y2) In this case the reciprocal is 1/(-110) or ... after a bit of hocus pocus with the sign ... -1/110
The quotient of a reciprocal would equal the numerator squared divided by the denominator squared. i.e. (x/y)/(y/x) = x2/y2
1/4 is the reciprocal of 4.
The reciprocal of any number is one divided by that number, so, the reciprocal of 4 is 1/4.

1/4 is the reciprocal of 4.
4 is the same as 4/1The reciprocal of a number is the flip of the fractionSo the reciprocal of 4 = 1/4
the reciprocal of 1 is 1/1 and the reciprocal of 1/4 is 4/1.
4 - y2 can be written as 22 - y2. This has become of the form of x2 - y2.Expansion for x2 - y2 is (x+y)(x-y).So, 4 - y2 = 22 - y2 = (2+y)(2-y)
The reciprocal of 2 is 1/2 (or .5) and the reciprocal of 4 is 1/4, or .25.
The reciprocal of any number is one divided by that number, so, the reciprocal of 4 is 1/4.
a reciprocal is just the number flipped over the reciprocal of 3 is 1/3 the reciprocal of 4/3 is 3/4
Reciprocal of 4 as a decimal is 0.25.
The reciprocal of 4/3 is 3/4.
