Answer 1

Respuesta:

Explicación paso a paso:

a)

x $4ab^2+4a^2-4b^2x-4ax\\\\\\=4\left(ab^2+a^2-b^2x-ax\right)\\\\\\=4\left(a^2+ab^2-xb^2-ax\right)$

______________________

b)

x $4a^2b^2-25m^2n^2\\\\\\=\left(2ab\right)^2-\left(5mn\right)^2\\\\\\=\left(2ab+5mn\right)\left(2ab-5mn\right)$

______________________

c)

x $7\left(y+2\right)-2y\left(y+2\right)\\\\\\=\left(y+2\right)\left(7-2y\right)$

______________________

d)

x = $2x\left(x-y\right)+m\left(x-y\right)\\\\\\2x\left(x-y\right)+m\left(x-y\right)$

_____________________

e)

$x\left(a-b\right)+2x\left(a-b\right)-\left(a-b\right)\\\\\\x =\left(a-b\right)\left(3x-1\right)$
