ln (x) (2 ln (x) + 1) = 2

x = e^{\frac{- 1 + 17}{4}}, x = e^{\frac{- 1 - 17}{4}}

Solution steps

ln (x) (2 ln (x) + 1) = 2

Rewrite the equation with

ln (x) = u

u (2 u + 1) = 2

Solve

u (2 u + 1) = 2 : u = \frac{- 1 + 17}{4}, u = \frac{- 1 - 17}{4}

u = \frac{- 1 + 17}{4}, u = \frac{- 1 - 17}{4}

Substitute back

u = ln (x),

solve for

x

Solve

ln (x) = \frac{- 1 + 17}{4} : x = e^{\frac{- 1 + 17}{4}}

Solve

ln (x) = \frac{- 1 - 17}{4} : x = e^{\frac{- 1 - 17}{4}}

x = e^{\frac{- 1 + 17}{4}}, x = e^{\frac{- 1 - 17}{4}}

Verify Solutions:

x = e^{\frac{- 1 + 17}{4}}

True

, x = e^{\frac{- 1 - 17}{4}}

True

The solutions are

x = e^{\frac{- 1 + 17}{4}}, x = e^{\frac{- 1 - 17}{4}}
