L = L + 4

L = \frac{1 + 17}{2}

Decimal Notation

L = 2.56155 \dots

Solution steps

L = L + 4

Square both sides:

L^{2} = L + 4

L^{2} = L + 4

Solve

L^{2} = L + 4 : L = \frac{1 + 17}{2}, L = \frac{1 - 17}{2}

L = \frac{1 + 17}{2}, L = \frac{1 - 17}{2}

Verify Solutions:

L = \frac{1 + 17}{2}

True

, L = \frac{1 - 17}{2}

False

The solution is

L = \frac{1 + 17}{2}
