3(x-2y)kuadrat 2 tolong di jwb btuh skrang

3(x - 2y)² = 3[(x - 2y)(x - 2y)]
                = 3[x² -4xy + 4y²]
                = 3x² - 12xy + 12y²
                

3 (x-2y)kuadrat
= (3*x-3*2y) kuadrat
= (3x-6y) kuadrat
= (3x-6y) (3x-6y)
=3x (3x-6y)-6y (3x-6y)
=9xkuadrat-18xy-18xy+36ykuadrat
=9xkuadrat-36xy+36ykuadrat
