Hei semua, Saya nak tanya sikit pasal pemfaktoran ungkapan kuadratik form 4.

a)2x+11x+5

Jawapan saya ialah (x+1) (2x+5)

jawapan dalam buku pula ialah (2x+1) (x+5)

Adakah jawapan kedua2nya adalah sama?? atau pun jawapan saya yang salah. Kalau boleh tolong tunjuk jalan kerja??

Boleh tolong???

jawapan ko salah. Betullah jawapannya (2x+1) (x+5)

Caranya:  2x*5 = 10x. Cari 2 hasil sebutan supaya hasil darab kedua-dua sebutan itu ialah 10x dan hasil tambahnya ialah 11x. Kemudian, bahagikan 2x dengan sebutan yg sesuai.        

2x/10x   dan   2x/x  = (2x+1) (x+5)
