Es para mñna ayuda con solución y explicación gracias

Answer 1

Explicación paso a paso:

1)

= m^2 + 14.m.n^2 + 49.n^4

= m^2 + 7.m.n^2 + 7.m.n^2 + 49.n^4

= (m). ( m+ 7.n^2) + (7.n^2). ( m+ 7.n^2)

= (m + 7.n^2) . ( m+ 7.n^2)

= ( m+ 7.n^2)^2)

2)

= 4.x^3y^4 + 8.x^2.y^5

= 4.x^2.y^4 ( x+2.y)

3)

= x^2 + x.y + x.z + y.z

= x. (x+y) + z. (x+y)

= (x + z) . (x+y)

4)

= 25x^4 - 9.y^2

= (5.x^2)^2 - (3.y)^2

= (5.x^2 + 3.y) . (5.x^2 - 3.y) .
