1.(2×+4) (×+1) 2.(2×+4) (×-1) 3.(2×-4) (×+1) 4.(2×-4) (×-1) Apa Jawabannya ????

1. ( 2x+4 ) (x+1)
= 2x (x+1) + 4 (x+1)
= 2x^2 + 2x + 4x +4
= 2x^2 + 6x + 4
2. (2x+4) (x-1)
= 2x (x-1) + 4 (x-1)
= 2x^2 - 2x + 4x - 4
= 2x^2 + 2x - 4
3. (2x-4) (x+1)
= 2x (x+1) - 4(x+1)
= 2x^2 + 2x - 4x + 4
= 2x^2 - 2x +4
4. (2x-4) (x-1)
= 2x(x-1) - 4(x-1)
= 2x^2 - 2x - 4x +4
= 2x^2 -6x +4



^_^

1) (2x+4) (x+1)
= 2x²+2x+4x+4
= 2x²+6x+4
-------------------- : 2
= x²+3x+2

2) (2x+4) (x-1)
= 2x²-2x+4x-4
= 2x²+2x-4
-------------------- : 2
= x²+x-2

3) (2x-4) (x+1)
= 2x²+2x-4x-4
= 2x²-2x-4
---------------------- : 2
= x²-x-2

3) (2x-4) (x-1)
= 2x²-2x-4x+4
= 2x²-6x+4
----------------------- : 2
= x²-3x+2

Semoga mwmbantu :)
