x/(v-5) - 3x/(v+5)
=x(v+5)-3x(v-5) / (v-5) (v+5)
=xv+5x-3xv-15x / (v-5) (v+5)
=-2xv-10x / (v-5)(v+5)
=-2x (v+5) /(v-5)(v+5)
=-2x / (v-5)
=x(v+5)-3x(v-5) / (v-5) (v+5)
=xv+5x-3xv-15x / (v-5) (v+5)
=-2xv-10x / (v-5)(v+5)
=-2x (v+5) /(v-5)(v+5)
=-2x / (v-5)
medhrk:
line two problem -*- =+, it will be +15x

x/(v-5)-3x/(v+5)
=x(v+5)-3x(v-5)/(v-5)(v+5)
=xv+5x-3xv+15x/(v-5)(v+5)
=20x-2xv/(v-5)(v+5)
=2x(10-v)/(v-5)(v+5)....
=x(v+5)-3x(v-5)/(v-5)(v+5)
=xv+5x-3xv+15x/(v-5)(v+5)
=20x-2xv/(v-5)(v+5)
=2x(10-v)/(v-5)(v+5)....
