1) -4x divided by x-x2 (squared)
-4x/(x-x^2)
=-4x/x(1-x)
=-4/(1-x)
2) 4w+wx divided by 7w
(4w+wx)/7w
=w(4+x)/7w
=(4+x)/7
3) 5x-5x2 divided by 25x-25
5x-5x2/25x-25
= 5x(1-x)/25(x-1)
=x(1-x)/5(x-1)
=x-x^2/(5x-5)
=-(x^2-x)/(5x-5)
=-x(x-1)/5(x-1)
=-x/5
4) 2x-2x2 divided by 8x-8
2x-2x^2/(8x-8)
=2x(1-x)/8(x-1)
=x(1-x)/4(x-1)
=x-x^2/4x-4
=-(x^2-x)/4x-4
=-x(x-1)/4(x-1)
=-x/4
5)-2x divided by 8
-2x/8
=x/-4
