Hitunglahlah.
1. 6a (a – 2).
2. (2x – 5y) × (-y).
3. (12x2 – 9xy) : (-3x).
4. (3ab + 4a) : 1/2 a.

6a (a – 2)
6a × a – 6a × 2
6a2 – 12a

Jadi, 6a (a – 2) = 6a2 – 12a.


(2x – 5y) × (-y)
2x × (-y) – 5y × (-y)
-2xy + 5y2.

Jadi, (2x – 5y) × (-y) = -2xy + 5y2.


(12x2 – 9xy) : (-3x).

\frac {12x^2} {-3x}\frac {9xy} {-3x}


-4x + 3y.

Jadi, (12x2 – 9xy) : (-3x) = -4x + 3y.


(3ab + 4a) : 1/2 a.

\frac {3ab} {1/2 a} + \frac {4a} {1/2 a}


6b + 8.

Jadi, (3ab + 4a) : 1/2 a = 6b + 8.
