1. = (x + 2) (x + 1) / 2x + 2
    = (x + 2) (x + 1) / 2 ( x + 1)
    = (x + 2) / 2

1. Di jabarkan terlebih dahulu agar lebih mudah
=  (X + 2) (X + 1) / 2X + 2
=  (X + 2) (X + 1) / 2 (X + 1)
=  (X + 2) / 2
2. Sama seperti di atas di jabarkan terlebih dahulu
= 2X - 6 / (X - 3) (X + 1)
= 2 (X - 3) / (X - 3) (X + 1)
= 2 / (X + 1)

Semoga bisa membantu :)
