(4a+b)² + (4a-b)²-2(8a+b)²

Answer 1

Respuesta:

$-96^{2} -32ab$

Explicación paso a paso:

$(4a+b)(4a+b)+(4a-b)^{2}-2(8a+b)^{2}$

$4a(4a+b)+b(4a+b)}+(4a-b)^{2}-2(8a+b)^{2}$

$16a^{2}+4ab}+b(4a+b)+(4a-b)^{2}-2(8a+b)^{2}$$16a^{2}+4ab+4ab+b^{2}}+(4a-b)^{2}-2(8a+b)^{2}$$16a^{2}+8ab+b^{2}+(4a-b)^{2}-2(8a+b)^{2}$
