Question

simplify:- 1+x/1-x - 1-x/1+x + 4x/1+x2 + 8x2​

Answer 1

Step-by-step explanation:

1+x/1-x-1-x/1+x+4x/1+2+8×2=0

4x+2+16=0

4x+18=0

2(2x+9)=0

2x+9=0

x=9/2

Answer 2

Answer:

=8x(1+x^3-x^5)/(1-x^4).

Step-by-step explanation:

=1+x/1-x -1-x/1+x +4x/1+x^2 +8x^2

=(1+x)^2 - (1-x)^2/(1+x)*(1-x) +4x/1+x^2 +8x^2

=1+x^2+2x-1-x^2+2x/(1-x^2) +4x/1+x^2 +8x^2

=4x/(1-x^2) +4x/1+x^2 +8x^2

=4x(1+x^2) + 4x(1-x^2)/(1-x^4) +8x^2

=4x+4x^3+4x-4x^3/(1-x^4) +8x^4

=8x/(1-x^4) +8x^2

=8x+8x^2(1-x^4)/(1-x^4)

=8x+8x^2-8x^6/(1-x^4)

=8x(1+x^3-x^5)/(1-x^4).
