Question

6x³+2x-3x²-1

2bx+cy+cx+2by

b⁴-b³+3b-3​

Answer 1

Explicación paso a paso:

A)

$6 {x}^{3} + 2x - 3 {x}^{2} - 1 = \\ (6 {x}^{3} + 2x) - (3 {x}^{2} + 1) \\ 2x(3 {x}^{2} + 1) - 1(3 {x}^{2} + 1) \\ (2 {x}^{2} - 1)(3 {x}^{2} + 1)respt$

B)

$2bx + cy + cx + 2by = \\ (2bx +2 by) + (cx + cy) = \\2 b(x + y) + c(x + y) = \\ (2b + c)(x + y)rpsta$

C)

${b}^{4} - {b}^{3} + 3b - 3 = \\ ( {b}^{4} - {b}^{3} ) + (3b - 3) = \\ {b}^{3} (b - 1) + 3(b - 1) = \\ ( {b}^{3} + 3)(b - 1)rspta$
