Kerjakan beserta caranya !

Menurut saya begini jawabannya

Nomor 1
= (x² - 25) / (x² + x - 20)
= (x - 5)(x + 5) / (x + 5)(x - 4)
= (x - 5) / (x - 4)

Nomor 2
= (2x² - 7x - 15) / (4x² - 9)
= (x - 5)(2x + 3) / (2x + 3)(2x - 3)
= (x - 5) / (2x - 3)

Nomor 3
= (8x - 20) / (2x² + 3x - 20)
= 4(2x - 5) / (2x - 5)(x + 4)
= 4 / (x + 4)

Nomor 4
= (x² - 9) / (x² + 8x + 15)
= (x - 3)(x + 3) / (x + 3)(x + 5)
= (x - 3) / (x + 5)


semoga berguna +_+
