Explain whether Sreedhar Acharya's formula is applicable or not in solving the equation `4x^(2)+(2x-1)(2x+1)=4x(2x-1)`.

Explanation

Given that `4x^(2)+(2x-1)(2x+1)=4x(2x-1)`
`4x^(2)+(2x)^(2)-(1)^(2)=8x^(2)-4x`
or, `4x^(2)+4x^(2)-1=8x^(2)-4x`
or, `8x^(2)-1=8x^(2)-4x`
or, `8x^(2)-1-8x^(2)+4x=0` or, `4x-1=0`, which is a linear equation.
Since the given equation is not a quadratic one, Sreedhar Acharya's formula is not applicable in solving the equation.
