Uprość wyrażenia : 4x-3(x+4)-12= -4k-2(k+3)-14k= -(7k-3)-15(4k-8)= 3c^-7c+15c(c-3)= -2x^-4x(x-5)+14x^= Jak co to ^ jest kwadrat ;)) Prosze o szybkie odpisanie

4x-3(x+4)-12 = 4x-3x-12-12 = x-24 -4k-2(k+3)-14k = -4k-2k-6-14k = -20k-6 -(7k-3)-15(4k-8) = -7k+3-60k+120 = -67k+123 3c^-7c+15c(c-3) = 3c^-7c+15c^-45c = 18c^-52c -2x^-4x(x-5)+14x^ = -2x^-4x^+20+14x^ = 12x^+20

4x-3(x+4)-12=4x-3x- 12-12=x-24 -4k-2(k+3)-14k=-20k-6 -(7k-3)-15(4k-8)=-67k +123 3c^-7c+15c(c-3)=18c² -52c -2x^-4x(x-5)+14x^=12x² +20
