Answer:

Using

b

a

=

a−b

a+b

Apply this property both sides, we get

3x

−x

+2x+3

3x

4

+x

2

−2x−3

=

5x

−2x

+7x−3

5x

−7x+3

2x

−4x−6

6x

=

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
