Question

помогите решить пожалуйста​

Answer 1

Ответ:

a) (a+b) ²=a²+2ab+b²

б) (b-c) ²=b²-2bc+c²

в)(d+3)²=d²+6d+9

г) (m-5)²= m²-10m+25

д) (c+1)²=c²+2c+1

e) (a-2)²=a²-4a+4

Answer 2

$(*+b)^2=a^2+2ab+b^2\\(a+b)^2=a^2+2ab+b^2\\\\(*-c)^2=b^2-2bc+c^2\\(b-c)^2=b^2-2bc+c^2\\\\(d+*)^2=*+6d+9\\(d+3)^2=d^2+6d+9\\\\(m-*)^2=*-10m+25\\(m-5)^2=m^2-10m+25\\\\(c+*)^2=*^2+*+1\\(c+1)^2=c^2+2c+1\\\\(a-*)^2=*^2-*+4\\(a-2)^2=a^2-4a+4$
