Question

1. Descomponemos en factores.

• 4x2 – 2xy + 2bx – by
• ay – by + az – bz
• 3uv – 3uw + 3u – v + w – 1
• 6abc+9bc+3c+8ab+12b+4

Answer 1

Explicación paso a paso:

Por agrupación de términos

• 4x2 – 2xy + 2bx – by

2x(2x-y)+b(2x-y)

=(2x-y)(2x+b)

• ay – by + az – bz

a(y+z) - b(y+z)

=(y+z)(a-b)

• 3uv – 3uw + 3u – v + w – 1

3u(v-w+1)-(v-w+1)

=(v-w+1)(3u-1)

• 6abc+9bc+3c+8ab+12b+4

3c(2ab+3b+1)+4(2ab+3b+1)

=(2ab+3b+1)(3c+4)
