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 + 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
