1/y-1/y-3 simplify the expression?

Question

simplify the expression

Answer 1

1/y-1/y-3 = (y-3)/y(y-3) - y/y(y-3)
= (y-3)-y/y(y-3)
= -3/y(y-3)

Answer 2

-3

Answer 3

I suspect you want some brackets to clarify ...
1/y - 1/y = 0
So 1/y - 1/y - 3 = -3

My guess, though, is that you mean

(1/y) - (1/(y-3))

Cross multiply to give a common denominator

= ((y-3) - y) / (y(y-3))

= -3 / (y^2 - 3y)

Answer 4

a million.Simplify the expression: a million/y - a million/y-3 a million/y - a million/(y - 3) liquid crystal show = y(y - 3) a million(y - 3)/[y(y - 3)] - 1y/[y(y - 3)] (y - 3 - y)/[y(y - 3)] -3/[y(y - 3)] 2) a. (a+b) (a-c) = a^2 - ac + ab - bc b. (3a^2+4b)/(ac+3b) = (3a^2+4b)/(ac+3b) 3) (x^2-10x+25)/(x^2-5x) aspect numerator and denominator [(x - 5)(x - 5)]/[x(x - 5)] (x - 5)/x 4. d(A, C) + d(B, C) [ 10 - (-5) + (10 - 3) = 15 + 7 = 22 5. x^ - 5 distinction of two squares a^2 - b^2 = (a + b)(a - b) 5 = [sqrt(5)]^2 [x + sqrt(5)][x - sqrt(5)]

Answer 5

1/y - 1/y leaves zero so then you're just left with the -3 as the answer.

Answer 6

Simplify 1/y-1/y-3.

(1/y) - (1/y) = 0
So
1/y-1/y-3 = -3

But I suspect you meant:
1/y - 1/(y - 3)

In that case:
1/y - 1/(y - 3) = {(y - 3) - y}/{y(y - 3)} = -3 / {y(y - 3)}

In the future please use parentheses to eliminate ambiguity.

Answer 7

1/y - 1/(y-3)=

Find the common denominator: y*(y-3)

(y-3)/ [y*(y-3)] - (y)/ [y*(y-3)] =

-3/ [y*(y-3)] =

-3/ (y^2-3y)

Answer 8

(y-3)-y/y(y-3)=
y-y-3/y^2-3y
-3/y^2-3y
