Question

ркшите плз раскрытьскопки (t+m)^2

(t-3)^2

(2t+1)^2

(3m-2t)^2

(3m^2+t^3)^2 срочно!

Answer 1

(t+m)^2 =t^2+2mt+m^2

(t-3)^2=t^2-6t+9

(2t+1)^2=4t^2+4t+1

(3m-2t)^2=9m^2-12mt+4t^2

 (3m^2+t^3)^2 =9m^4+6m^2t^3+t^6 

Answer 2

(t + m) ^2= t^2 + 2tm + m^2
(t-3)^2=t^2 - 6t + 9

(2t + 1)^2=4t^2 + 4 t+ 1

 (3m - 2t)^2=9m^2-12mt+4t^2

(3m^2 + t^3)^2 = 9m^4 +6m^2t^3 + t^6
