Answer:
Using
b
a
=
a−b
a+b
Apply this property both sides, we get
3x
4
−x
2
+2x+3
3x
4
+x
2
−2x−3
=
5x
4
−2x
2
+7x−3
5x
4
+2x
2
−7x+3
⇒
2x
2
−4x−6
6x
4
=
4x

−14x+6
10x

When x=0, the equation is satisfied. So, one solution is zero.
Now, when x is not equal to zero, cancel x
4
on both sides and cancel factor of 2 in the denominator and numerator
⇒
x
2
−2x−3
3
=
2x
2
−7x+3
5
Now after cross multiplying and simplifying the equation, we get
⇒x
2
−11x+24=0
⇒(x−8)(x−3)=0
So, 3 and 8 are also the solution of equation.
So, x=0,3,8 are the solutions
