Prosze rowniez z obliczeniami :) (4k-m) (x-6x2 +x3) = (-3p-2q) (7p+6q) = (5x2+3) (2x2-x+4) = (-0,3+x) (x+0,3) = (k2+k+1) (k2-k+1) = (1+2x+x2) (1-2x+x2) = Bardzo dzienkuje za pomoc akurat z tego jestem slaby :D

(4k-m)(x-6x2+x3)=4kx-24kx2+4kx3-mx+6mx2-mx3 (-3p-2q)(7p+6q)=-21p2-18pq-14pq-12q2=-21p2-32pq-12q2 (5x2+3)(2x2-x+4)=10x4-5x3+20x2+6x2-3x+12=10x4-5x3+26x2-3x+12 (-0,3+x)(x+0,3)=(x-0,3)(x+0,3)= x2-0,09 (k2+k+1)(k2-k+1)=k4-k3+k2+k3-k2+k+k2-k+1=k4+k2+1 (1+2x+x2)(1-2x+x2)=1-2x+x2+2x-4x2+2x3+x2-2x3+x4=1+x4-2x2
