If `I=int(((2x-1)cos(sqrt(4x^2-4x+6)))/sqrt(4x^2-4x+6))dx`

The integral int((2x-1)cossqrt((2x-1)^2+5))/(sqrt(4x^2-4x+6))dx is equal to :(where c is constant of integration)

sqrt(x^(2)+6x-4)dx

int(1)/(sqrt(4x^(2)-x+4))dx

int((x-2 )dx)/(sqrt(x^(2)-4x+3)

int(2x-7)/(sqrt(4x-1))*dx

int (4x-1) sqrt(x^2-x-2) dx

int(dx)/(sqrt(1+4x^(2)))

int(dx)/(sqrt(1+4x^(2)))

int(dx)/(sqrt(4x^(2)+1))

int sqrt((x^(2)-4x+2))dx
