-------------------
36b²c/(a²+14a +49)
:
18bc²
/
(a² -49) =36b²c
/
(a²+2a*7+7²)
:
18bc²
/
(a² -7²) =
36b²c/(a+7)²
:
18bc²
/
(a -7) *(a+7) =36b²c
/
(a+7)² * (a -7) (a+7) / 18bc² =
36b²c*(a -7)*(a+7)
/
18bc²(a+7)² =
2b(a -7) / c(a+7).

36b²c/(a²+14a +49) : 18bc²/(a² -49) =36b²c/(a²+2a*7+7²) : 18bc² /(a² -7²) =
36b²c/(a+7)² : 18bc²/ (a -7) *(a+7) =36b²c/(a+7)² * (a -7) (a+7) / 18bc² =
36b²c*(a -7)*(a+7) / 18bc²(a+7)² = 2b(a -7) / c(a+7).
