1.7.56×1.09+1.09×6-12.56×1.092.a(x+y)+b(x+y)

1.7.56×1.09+1.09×6-12.56×1.092.a(x+y)+b(x+y)
1.7.56×1.09+1.09×6-12.56×1.09
2.a(x+y)+b(x+y)

1.7.56×1.09+1.09×6-12.56×1.092.a(x+y)+b(x+y)
1.
7.56×1.09+1.09×6-12.56×1.09
=1.09×(7.56+6-12.56)
=1.09×1
=1.09
2.
a(x+y)+b(x+y)
=(x+y)(a+b)

1. 7.56×1.09+1.09×6-12.56×1.09
=1.09×(7.56+6-12.56)
=1.09
2. a(x+y)+b(x+y)=(a+b)(x+y)

1. 7.56×1.09+1.09×6-12.56×1.09
=1.09×(7.56+6-12.56)
=1.09×1
=1.09
2. a(x+y)+b(x+y)
=(x+y)(a+b)

1.=1.09(7.56+6-12.56)
2.=(a+b)(x+y)

7.56×1.09+1.09×6-12.56×1.09
=(7.56+6-12.56)×1.09
=1×1.09
=1.09
a(x+y)+b(x+y)
=(x+y)(a+b)

1.1.09*（7.56+6-12.56）=1.09*1=1.09
2.ax+ay+bx+by=(a+b)x+(a+b)y=(a+b)(x+y)
