1. ( ax+x²)²
(2a-3y²)²
(3supra2 a²+x³)²
(0,2x - 5ay)²
(3x+√2)² ( va rog help mee)

Răspuns :

[tex]a)(ax+x^2)^2=a^2x^2+2ax^3+x^4=x^2(a^2+2ax+x^2)=[x(a+x)]^2\\ b)(2a-3y^2)^2=4a^2-12ay^2+9y^4\\ c)(\frac{3}{2}a^2+x^3)^2=\frac{9a^4}{4}+3a^2x^3+x^6\\ d)(0,2x-5ay)^2=0,04x^2-2xay+25a^2y^2\\ (3x+\sqrt2)^2=9x^2+6x\sqrt2+2[/tex]
