Question

Agrupamento=> ac + bc + ad + bd=(a+b)+d(a + b) = (a + b) (c + d)

A) ax-ay+bx-by

B) 5ax-5ay+bx-by

C) x²+ 5x + ax + 5a

D) 6a² + 2ab - 3ac - bc

Answer 1

a) ax - ay+ bx -by
a(x-y) + b( x-y)
(a+ b) * ( x-y)
b) 5ax- 5ay+bx-by
5a( x-y) + b( x -y)
(5a + b) * ( x-y)
c) x2 + 5x+ax + 5a
x( x + 5) + a ( x+5)
(x + a) * ( x + 5)
d) 6(a)2+2ab -3ac -bc
2a( 3a + b) - c ( 3a + b )
( 2a - c ) * ( 3a + b )
