va rog urgent dau coroana

Answer 1

(a+2)/(6-a) -(a-2)/(6-a) =(a+2-a+2)/(6-a) = 4/(6-a)

1/a +(a+3)/x^2 =(a+a+3)/a^2 = (2a+3)/a^2

Answer 2

$\frac{(a + 2)}{(6 - a)} - \frac{(a - 2 - a + 2)}{(6 - a)} = \frac{4}{(6 - a)}$
$\frac{1}{a} + \frac{(a + 3)}{x 2} = \frac{(a + a + 3)}{a ^{2} } = \frac{(2a + 3)}{a ^{2} }$
Succes!
