# Math Help - please help me to solve this.....

solve the equation 1n x + 1n(X+2) =1...thank u

Hey sharmala.

Is Inx meant to be ln(x) where ln is the natural logarithm?

yes....

Well here is the main hint: ln(x) + ln(y) = ln(x*y).

i tried but the answer is incorrect

Show us what you tried.

ln(x)+ln(x+2) = ln(x*(x+2))

You then need to clear it of the logarithm, by taking the exponential of both sides of the equation.

e^[ln(x*(x+2))] = e^1
x^2 + 2x = e^1
x^2 + 2x - e^1 = 0

And then solve using the quadratic formula.
