w zadaniu 1 tylko te zaznaczone kreska i w drugim tak samo
Ćw.1
a) 18x2+6x= 6x(3x+1)
b) 47m2-19m= m(47m+19)
c) -12kl+30k2l2= 6kl(-2+5kl)
d) 16xyz-48xy+60yz= 4y(4xz-12x+15z)
Ćw.2
a)18x2y+24xy2-36xy= 6x(3x+4y2-6y)
=-3y(-6x2-8xy+12x)
b)15a2c2+2a3c3-10a2c2= a2c2(15+2ac-10)
= 2ac(7,5ac+ac-5ac)
c) 3/4p2qr - 1/8pq2r - 5/12pqr2 = pqr(3/4p-1/8q-5/12r)
= -1/4q(3p2r-1/2pqr-5/3pr)
