b) ( 4m+ 2n)^2=
c) ( 8x^2+2xy)^2)=

Answer 1

a) (3+2m)^2
9+ 12m+ m^2

b) (4m+2n)^2
16m^2 +16m.n + 4n^2

c) (8x^2 + 2xy)^2
64x^2 + 32x^3y+ 4x^2y^2

Answer 2

Boa tarde!

a)

(3 + 2m)² = 

3² + 2.3.2m + (2m)² = 

9 + 12m + 4m²

------------------------------------

b)

(4m + 2n)² = 

(4m)² + 2.4m.2n + (2n)² = 

16m² + 16mn + 4n²

---------------------------------------

c)

(8x² + 2xy)² = 

(8x²)² + 2.8x².2xy + (2xy)² = 

64x^4 + 32x³y + 4x²y²
