Question

Factoriza aplicando factor común por agrupamiento
• 2x2-xy+10x-5
• X3-x2y-3x+3y
• 3x-ax+bx-3y+ay-by
• X2n-1-3xny+xn-1y-3y2
• 3a(x-y)+y-x
• 3xm-5x2m-xm+1
• Y4 -y3-y+1
• -1+x+x2(x-1)

Answer 1

• X3-x2y-3x+3y


• 3x-ax+bx-3y+ay-by
• X2n-1-3xny+xn-1y-3y2
• 3a(x-y)+y-x
• 3xm-5x2m-xm+1

• Y4 -y3-y+1
$y^{4} - y^{3} - y + 1$

$y^{3} (y-1) - (y-1)$

$(y-1)( y^{3} -1)$

(y-1) (y-1)($y^{2} +y+1)$

• -1+x+x2(x-1)
(x-1)(1 +$x^{2}$)
