Question

necesito ayuda con mi tarea de matemáticas

Answer 1

a). ac-ad+bc-bd
(ac-ad)+(bc-bd)
a(c-d)+b(c-d)
(c-d) (a+b)

b).3ax-ay+9bx-3by
(3ax-ay)+(abx-3by)
a(3x-y)+3b(3x-y)
(3x-y)(a+3b)

c).18mx-6my+54nx-18ny
(18mx-6my)+(54nx-18ny)
2m(9x-3y)+6n(9x-3y)
(9x-3y)(2m+6n)

d)4ax+ay+12x^2+3xy
(4ax+ay)+(12x^2+3xy)
a(4x+y)+3x(4x+y)
(4x+y)(a+3x)

e).3xy-3xz+3x-y+z-1
(3xy-y)-(3xz-z)+(3x-1)
y(3x-1)-z(3x-1)+(3x-1)
(3x-1)(y-z)

f).2ab-2ac+2a-b-c-1
(2ab-b)-(2ac-c)+(2a-1)
b(2a-1)-c(2a-1)+(2a-1)
(2a-1)(b-c)

g).2ax+5bx+2ay+5by
(2ax+2ay)+(5bx+5by)
2a(x+y)+5b(x+y)
(x+y)(2a+5b)

h).5xp+5py-3ax-3ay
(5xp+5py)-(3ax+3ay)
5p(x+y)-3a(x+y)
(x+y)(5p-3a)

espero que te sirva.
