Explicação passo a passo:

$\mathsf{a)\:(x - y)^2 = x^2 - 2xy + y^2}$

$\mathsf{b)\:(3a - 4b^2)^2 = 9a^2 - 24ab^2 + 16b^4}$

$\mathsf{c)\:(x^2 + 7y).(x^2 - 7y) = x^4 - 49y^2}$

$\mathsf{d)\:(4 - x^2y) = 16 - 8x^2y + x^4y^2}$

$\mathsf{e)\:(3x + 2y)^2 = 9x^2 + 12xy + 4y^2}$

$\mathsf{f)\:(a^3 + 5b)^2 = a^6 + 10a^3b + 25b^2}$

$\mathsf{g)\:(a^3 + 5b).(a^3 + 5b) = a^6 + 10a^3b + 25b^2}$
