Question

Fatore:

a) 8x + 8y + cx + cy=

b) ab – ac –xb + yc =

c) 2ax – 2ay – 6bx + 6by =

d) x⁴ + 9x³ – 6x – 54=

e) ax – a + mx/3 – m/3 =

Answer 1

a) 8(x+y)+c(x+y) = (8+c)(x+y)
b)a(b-c) -c(b-c)= (a-c)(b+c)
c)2a(x-y) - 6b(x+y)= (2a-6b)(x-y)
d)x3 (x+9)-6(x-9)= (x3-6)(x+9)
e)a(x-1)+m/3(x-1)= (a+m/3)(x-1)
