Evaluate: `int1/(sqrt(5x^2-2x))\ dx`

Text Solution

Verified by Experts

`I=int1/(sqrt(5x^2-2x))\ dx`
`I=int1/((sqrt5)(sqrt(x^2-2/5x)))\ dx`
`I=int1/((sqrt5)(sqrt(x^2-2/5x+(1/5)^2-(1/5)^2))\ dx`
`I=int1/((sqrt5)(sqrt(x-1/5)^2-(1/5)^2))\ dx`
`I=int1/(sqrt5)log(x-1/5+(sqrt(x-1/5)^2-(1/5)^2)+c`
`I=int1/(sqrt5)log(x-1/5+(sqrt(5x^2-2x))+c`
