Rozwiąż nierówności: -2(x+1)(x-2)
a) (x+2)^-(x+3)^=2(3x-5)
b) 5x-4(x-6)=2(x+1)^-2(x+1)(x-2)
x^+4x+4-x^+6x+9=6x-10
10x+9=6x-10
10x-6x=-10-9
4x=-19/:4
x=-4,75
b) 5x-4(x-6)=2(x+1)^-2(x+1)(x-1)
5x-4x+24=2(x^+2x+1)-2(x-1)^
x+24=2x^+4x+2-2(x^-2x+1)
x+24=2x^+4x+2-2x^+4x+2
x+24=8x+4
24-4=8x-x
20=7x/:7
x=2 i 6/7
