Question

Operar los siguientes cuadrados de binomios.
​

Answer 1

Respuesta:

$(\sqrt{2} +2)^{2} \\\\\left(\sqrt{2}\right)^2+2\sqrt{2}\cdot \:2+2^2\\\\2 +4\sqrt{2}+4\\\\6+4\sqrt{2}$

$(\sqrt{3} -\sqrt{5})^{2} \\\\\sqrt{3}^{2} -2(\sqrt{3})(\sqrt{5})+\sqrt{5}^{2} \\\\3-2\sqrt{15}+5\\\\8-2\sqrt{15}$

$(2\sqrt{3} + 3\sqrt{5})^{2} \\\\\left(2\sqrt{3}\right)^2+2\cdot \:2\sqrt{3}\cdot \:3\sqrt{5}+\left(3\sqrt{5}\right)^2\\\\4^{2}( \sqrt{3}\right))^2+ 12\sqrt{15} + 3^{2}( \sqrt{5}\right))^2\\\\12+12\sqrt{15}+45\\\\57+12\sqrt{15}$

$(\sqrt{5} -2\sqrt{2} )^{2} \\\\\left(\sqrt{5}\right)^2-2(\sqrt{5}\cdot \:2\sqrt{2})+\left(2\sqrt{2}\right)^2\\\\5 -4\sqrt{10}+2^{2} (\sqrt{2})^{2} \\\\8+5-4\sqrt{10}\\\\13-4\sqrt{10}$
