Para calcular (x+3)2(x+3)^2, usaremos a fórmula de binômio ao quadrado, que é (a+b)2=a2+2ab+b2(a + b)^2 = a^2 + 2ab + b^2, onde a=xa = x e b=3b = 3.

Substituindo aa e bb na fórmula, temos:

(x+3)2=x2+2x3+32 (x + 3)^2 = x^2 + 2 \cdot x \cdot 3 + 3^2

Calculando os termos:

x2+6x+9 x^2 + 6x + 9

Portanto, (x+3)2=x2+6x+9(x+3)^2 = x^2 + 6x + 9.
