Soal:
Tentukan hasil dari:
• 8a + 3b - 2b + 9a =……
• 4( 2a + 5 ) =……
• 8( x^2 + x - 1 ) =……
• 3( 4p + q + r ) =……






pakai cara
ngasal = auto report ​

Nomor 1:

8a + 3b - 2b + 9a

= 8a + 9a + 3b - 2b

= 17a + b✔

Nomor 2:

4( 2a + 5 )

= (4 × 2a) + (4 × 5)

= 8a + 20✔

Nomor 3:

8( x² + x - 1 )

= (8 . x²) + (8 . x) + (8 . (-1)

= 8x² + 8x - 8✔

Nomor 4:

3( 4p + q + r )

= (3 × 4p) + (3 × q) + (3 × r)

= 12p + 3q + 3r✔

1. 8a + 3b - 2b + 9a

= 8a + 9a + 3b - 2b

= 17a + b

2. 4(2a + 5)

= 4.2a + 4.5

= 8a + 20

3. 8(x² + x - 1)

= 8.x² + 8.x + 8.(-1)

= 8x² + 8x - 8

4. 3(4p + q + r)

= 3.4p + 3.q + 3.r

= 12p + 3q + 3r
