Answer 1

Respuesta:

Explicación paso a paso:

a)   $(d+e)^{2} = d^{2} + 2de + e^{2}$

b)   $(6p-2r)^{2} = (6p)^{2} - 2(6p)(2r) + (2r)^{2}$

     $(6p-2r)^{2} = 36p^{2} - 24pr + 4r^{2}$

c)   $(\sqrt{2}x -\sqrt{2}y )^{2} = (\sqrt{2}x)^{2}-2(\sqrt{2}x)(\sqrt{2}y)+(\sqrt{2}y)^{2}$

     $(\sqrt{2}x -\sqrt{2}y )^{2} = \sqrt{2}^{2}x^{2}-2\sqrt{2}^{2}xy+\sqrt{2}^{2}y^{2}$

     $(\sqrt{2}x -\sqrt{2}y )^{2} = 2x^{2}-4xy+2y^{2}$

d)   $(\frac{3}{2}f+2d)^{2} = (\frac{3}{2}f)^{2} + 2(\frac{3}{2}f)(2d)+(2d)^{2}$

     $(\frac{3}{2}f+2d)^{2} = \frac{9}{4}f^{2} + 6fd+4d^{2}$
