Oblicz wyrażenia algebraiczne: (-5z - 1) + (-6z + 2) = (2x - 3y) + (3y - 2x) = 2a-3(3a-2) = (2a-3b)+(a-4b)+(-2a-3b) = (2a2-a+4)+(a2+4a-3) = 6m-2m+1)-(m-4) = -2x(x-8y+7) = Potrzebne na jutro, dam naj.

(-5z - 1) + (-6z + 2) = -5z -1-6z+2= -11z+1(2x - 3y) + (3y - 2x) = 2x-3y+3y-2x=0  2a-3(3a-2) = 2a-9a+6= -7a+6  (2a-3b)+(a-4b)+(-2a-3b) = 2a-3b+a-4b-2a-3b= a- 10b  (2a²-a+4)+(a²+4a-3) = 2a²-a+4+a²+4a-3= 3a²+3a+1  (6m-2m+1)-(m-4) = 6m-2m+1-m+4= 3m+5  -2x(x-8y+7) = -2x²+16xy-14x

(-5z - 1) + (-6z + 2)= -5z-1-6z+2=-11z+1 (2x - 3y) + (3y - 2x)= 2x-3y+3y-2x=0 2a-3(3a-2)= 2a-9a+6=-7a+6 (2a-3b)+(a-4b)+(-2a-3b)= 2a-3b+a-4b-2a-3b=-10b+a (2a2-a+4)+(a2+4a-3)= 2a2-a+4+a2+4a-3=3a2+3a+1 (6m-2m+1)-(m-4)= 6m-2m+1-m+4=3m+5 -2x(x-8y+7)= -2x2+16xy-14x Mam nadzieję, że pomogłam :) :)
