Question

решить:

(x-y)10

(a+b-c)2

(a-b)5a

a(x-y)

(a-b)(-6)

2(a+b)+4(a+b)

4-2(x+1)

2(a-b)-3(a+b)

4(x-y)+7(x-y)

2a-3(b-a)

a(x-y)-b(x+y)

Answer 1

(x-y)10 =10*x-10*y
(a+b-c)2 =-2*c+2*b+2*a
(a-b)5a =5*a^2-5*a*b
a(x-y) =a*x-a*y
(a-b)(-6) =6*b-6*a
2(a+b)+4(a+b) =6*b+6*a
4-2(x+1) =2-2*x
2(a-b)-3(a+b) =-5*b-a
4(x-y)+7(x-y) =11*x-11*y
2a-3(b-a) =5*a-3*b
a(x-y)-b(x+y) =(-b-a)*y+(a-b)*x

Answer 2

(х-у)10=10х-10у

 (a+b-c)2= 2а+2b-2c

 (a-b)5a=5a*a-5ab

 a(x-y)=ax-ay

 (a-b)(-6)=-6a+6b

 2(a+b)+4(a+b)=2a+2b+4a+4b=6a+6b

 4-2(x+1)=4-2x-2=2-2x

 2(a-b)-3(a+b)=2a-2b-3a-3b=-a-5b

 4(x-y)+7(x-y)=4x-4y+7x-7y=11x-11y

 2a-3(b-a)=2a-3b+ab

 a(x-y)-b(x+y) = ax-ay-bx-by
