Може бути не правельно
1) (m+4)^2=m^2+2m*4+4^2=m^2+8m+16
2) (c-b)^2=c^2-2cb+b^2=c^2-2bc+b^2
3) (x+y)^2=x^2+2xy+y^2
4) (p-q)^2=p^2-2pq+q^2
5) (a-3)^2=a^2-2a*3+3^2=a^2-6a+9
6) (b+4)^2=b^2+2b*4+4^2=b^2+8b+16
7) (2х-у)^2=(2х)^2-2*2xy+y^2=4x^2-4xy+y^2
8) (-2-а)^2=4+4a+a^2=a^2+4a+4
9) (1/2+b)^2=(1/2)^2+2*1/2b+b^2=1/4+b+b^2
10) (0,3-у)^2=(3/10-y)^2=9/100-3/5y+y^2=0.09-0.6y+y^2
