c si d va rog .....
.........​

Answer 1

c) (ax)^2+2ax×x^2+(x^2)^2=a^2x^2+2ax^3+x^4

d) 4a^2-2×2a×(-3y^2)+9y^4=4a^2+12ay^2+9y^4

Answer 2

Răspuns:

${(ax + {x}^{2})}^{2} = {a}^{2} {x}^{2} + 2a {x}^{3} + {x}^{4} \\ {(2a - 3 {y}^{2}) }^{2} = 4 {a}^{2} - 12a {y}^{2} + 9 {y}^{4}$

Sper ca nu am gresit nici un calcul
