ln(x+9)+ln(x-5)=2ln(x)

ln (x + 9) + ln (x - 5) = 2 ln (x)

x = \frac{45}{4}

Decimal Notation

x = 11.25

Solution steps

ln (x + 9) + ln (x - 5) = 2 ln (x)

Apply log rules

(x + 9) (x - 5) = x^{2}

Solve

(x + 9) (x - 5) = x^{2} : x = \frac{45}{4}

x = \frac{45}{4}

Verify Solutions:

x = \frac{45}{4}

True

The solution is

x = \frac{45}{4}

x ln (x) = 6 ln (x)

\frac{4 ln ( x )}{x} = 5

lo g_{2} ((r + 4)^{2}) = 6

ln (x) + 2 x - 2 = 0

50 = 9.4177 ln (x) + 59.156
