Answer 1

a) $4 x^{3} -8 x^{2}y -4x y^{2} -32b x^{2} = -( 8 x^{2} y+4x y^{2} ) +( 4x^{3} -32b x^{2})$
 
$-( 8 x^{2} y+4x y^{2} ) +( 4x^{3} -32b x^{2}) = -4xy(x+4y) + 4 x^{2} ( x -8b) = (-4xy+4x)(x+4y)(x-8b)$
Obten el termino que se repite en todas y lo restas [/tex]

b) $[tex]5x ( x^{2} -xy+2 y^{2} )-( x^{2} -xy+2 y^{2} )= (5x-1)(x^{2} -xy+2 y^{2})$ [/tex]

c) $100 x^{4} -49 = (10 x^{2} +7)(10 x^{2} -7)$

d) $64 x^{3} -27 = (4x -3)(16 x^{2} +12x+9)$

e) $125 y^{6} +8= (5 y^{3}+2)(25 y^{3} -10y+2)$

f) $16 y^{4} +1 = (4y^{2} + 2y+1)(4y^{2} - 2y+1)$

g) $x^{9} -1 = (x^{2} -1)( x^{4} +2 x^{2} +1)$
