Question

Sederhanakanlah bentuk aljabar berikut:
1. 2x² +3x-9/x² +2x-3 =

2. x² -5x-6/x+1

3. 3b-bx/cx-3c

4. 3x² -27/x²+2x-3

5. 2x²-5x-12/x²-16

6. -x²-2x+35/x²-25

Answer 1

1. (2x - 3) (x + 3)/(x - 1) (x + 3)
     = 2x - 3 / x - 1
2.  (x-6)(x+1)/(x+1)
     = x - 6
3. b(3-x)/c(x-3)
4. (3x-9)(x+3)/(x-1)(x+3)
     = 3x - 9 / x - 1
     = 3 (x-3)/(x-1)
5. (2x+3)(x-4)/(x-4)(x+4)
     = 2x + 3 / x + 4
6. (x-7)(x+5)/(x-5)(x+5)
     = x-7 / x-5

maaf kalo ada yang salah
