Which is equivalent to 4X over X -7 minus X +7 over X?

Answer 1

The expression can be simplified as follows:

4X/(X-7) - (X+7)/X

Combining the fractions into a single fraction with a common denominator, we get:

(4X*X - (X-7)(X+7))/(X(X-7))

Expanding the terms in the numerator, we get:

(4X^2 - (X^2 - 7X +X - 7))/(X(X-7))

Simplifying further:

(4X^2 - X^2 + 7X - X - 7)/(X(X-7))
(3X^2 + 6X - 7)/(X(X-7))

Therefore, 4X/(X-7) - (X+7)/X is equivalent to (3X^2 + 6X - 7)/(X(X-7))
