Respuesta:

ESPERO TE AYUDE

Explicación paso a paso:

$\frac{X^{2}-Y^{2} }{X+Y} =\frac{(X+Y)(X-Y)}{X+Y} =X-Y\\\\\frac{Y^{2}-X^{2} }{Y+X} =\frac{(Y+X)(Y-X)}{Y+X}=Y-X\\\\\frac{25 -X^{2} }{25-X} = \frac{5^{2}-X^{2} }{25-X} =\frac{(5+X)(5-X)}{25+X}\\\\\frac{X^{3}-1 }{X+1} = \frac{X^{3}-1^{3} }{X+1}=\frac{(X-1)(X^{2}+X+1)}{X+1}$
