1. Jawaban teguh088
1. 4x²-6x/-2x²-5x+12 = 2x.(2x-3) / -1.(2x-3).(x+4) = -2x/(x+4)
2. -2x²-5x+3/2x²-7x+3 = -1.(2x-1)(x+3) / (2x-1)(x-3) = -(x+3)/(x-3) = (x+3)/(3-x)
3. x²-1/x²+2x-3 = (x-1)(x+1) / (x+3)(x-1) = (x+1)/(x+3)
4. 7x²+41x-6/2x²+15x+18 = (7x-1)(x+6) / (2x+3)(x+6) = (7x-1)/(2x+3)
5. 8x²-8x/5x²+x-6 = 8x(x-1) / (5x+6)(x-1) = 8x/(5x+6)
