Question

Desenvolva os produtos notáveis:
C) (2a + 4)2
E) [xy + 1/3x]2
G) (x3 + y2)2
F) ( A2 + ab3)2

Answer 1

C)(2a+4)2=4a+8
E)(xy+1/3x)2=2xy+2/3x
G)(x³+y²)2=2x³+2y²
F)(A²+ab³)2=2a²+2ab³

Answer 2

Boa  tarde

(x + y)² = x² + 2xy + y²

c) 

(2a + 4)² = 4a² + 16a + 16 

e)

(xy + x/3)² = x²y² + 2x²y/3 + x²/9 

g)

(x^3 + y^2)² = x^6 + 2x^3y^2 + y^4

f)

(a^2 + ab^3)² = a^4 + 2a^3b^3 + a^2b^6
