Tentukan bentuk sederhana Aljabar berikut :

Penjelasan dengan langkah-langkah:

Nomor 1

3x (4y + 2) – 3 ( 6y – 5x )

= 3x(4y) + 3x(2) – 3(6y) + 3(5x)

= 12xy + 6x – 18y + 15x

= 12xy + 6x + 15x – 18y

${ boxed{ boxed{ rm = 12xy + 21x - 18y}}}$

Nomor 2

3(2y – 5x) – 5(x + 3y)

= 3(2y) – 3(5x) – 5(x) – 5(3y)

= 6y – 15x – 5x – 15y

= -15x – 5x + 6y – 15y

${ boxed{ boxed{ rm= -20x - 9y}}}$

Nomor 3

6y( x – 3 ) – 2x ( y + 1 ) + x – 2

= 6y(x) – 6y(3) – 2x(y) – 2x + x – 2

= 6xy – 18y – 2xy – x -2

${ boxed{ boxed{ rm = 4xy - x - 18y - 2}}}$

Nomor 4

(5x + 8y) – (4y – 5 – 6y)

= 5x + 8y – ( -2y – 5 )

= 5x + 8y + 2y – 5

${ boxed{ boxed{ rm = 5x + 10y -5}}}$

Nomor 5

(3p + q) + (–8p – 9q + 7p)

= 3p + q + ( -8p + 7p – 9q )

= 3p + q + ( -p – 9q )

= 3p – p + q – 9q

${ boxed{ boxed{ rm = 2p - 8q}}}$

1) 3x (4y + 2) – 3(6y – 5x)

= 12xy + 6x – 18y + 15x

= 6x + 15x – 18y + 12xy

= 21x – 18y + 12xy

2) 3(2y – 5x) – 5(x + 3y)

= 6y – 15x – 5x – 15y

= -15x – 5x + 6y – 15y

= -20x – 9y

3) 6y ( x – 3) – 2x (y + 1) + x – 2

= 6xy – 18y – 2xy – 2 + x – 2

= x – 18y + 6xy – 2xy – 2 – 2

= x – 18y + 4xy – 4

4) (5x + 8y) – (4y – 5 – 6y)

= 5x + 8y – 4y + 5 + 6y

= 5x + 8y – 4y + 6y + 5

= 5x + 10y + 5

5) (3p + q) + (–8p – 9q + 7p)

= 3p + q – 8p – 9q + 7p

= 3p – 8p + 7p + q – 9q

= 2p – 8q

Maaf kalo salah ^_^
