Question

desarrolla a) (x+1) (y-1) ayudaaa​

Answer 1

Respuesta:

(x+1)(y-1)

resupuesta

xy-x+y-1

Answer 2

A) (x+1) (y-1)=

= (x+1) [(y+(-1) ]

= x(y) + x(-1) +1(y) +1(-1)

= xy -x + 1y -1

R//= xy -x + 1y -1

B) (x-1) (y-1)=

= [x+(-1)] [y+(-1)]

= x(y) + x(-1) + (-1)(y) +(-1)(-1)

= xy -x -y + 1

R//= xy -x -y + 1

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

= (2x+2) [(-y) +2]

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

= 2xy + 4x -2y +4

R//= 2xy + 4x -2 + 4

D) (-x-2) (2y -3)=

= [(-x)+2)] [2y+(-3)]

= (-x)(2y) + (-x)(-3) + (-2)(2) + (-2)(-3)

R//= -2yx + 3x -4y + 6

E) (xy-x) (y+10)=

= [xy+(-x)] (y+10)

= xy(y) +xy(-10) + (-x)(y) + (-x)(10)

R//= xy² + 10xy -xy -10x

F) (2xy-y) (5x-3)=

= [2xy(-y)] [5x(-3)]

= 2xy(5x) + 2x(-3) + (-y)(5x) + (-y)(-3)

R//=10x²y -6xy -5xy + 3y

Espero te sirva de ayuda <3
