Question

Resolva
A)(×-2)2
B)(5×+y)2
C)(6×2-y3)
D)(a+2×)2

Answer 1

Resposta:

A)  $x^{2} - 4x + 4$; B)  $25x^{2} + 10xy + y^{2}$; C)  $216x^{6} - 108x^{4} y - y^{3}$; D)  2$a^{2} + 4ax + 4x^{2}$

Explicação passo a passo:

A) $(x-2)^{2}$ = $x^{2} - 4x + 4$

B) $(5x+y)^{2}$ = $25x^{2} + 10xy + y^{2}$

C) $(6x^{2}-y)^{3}$ = $216x^{6} - 108x^{4} y - y^{3}$

D) $(a+2x)^{2}$ = 2$a^{2} + 4ax + 4x^{2}$
