ln(x^2-x-1)=0

Solution

ln (x^{2} - x - 1) = 0

Solution

x = 2, x = - 1

Solution steps

ln (x^{2} - x - 1) = 0

Apply log rules

x^{2} - x - 1 = 1

Solve

x^{2} - x - 1 = 1 : x = 2, x = - 1

x = 2, x = - 1

Popular Examples

log_{3}(2x^2+5x+4)-7=2

lo g_{3} (2 x^{2} + 5 x + 4) - 7 = 2

(log_{10}(6-x^2))/(log_{10)(3x-4)}=2

\frac{lo g _{10} ( 6 - x ^{2} )}{lo g _{10} ( 3 x - 4 )} = 2

log_{4}(x+12)-log_{4}(5-x)=2

lo g_{4} (x + 12) - lo g_{4} (5 - x) = 2

lo g_{2} (x + 7) = 5

log_{b}(3)= 1/2

lo g_{b} (3) = \frac{1}{2}
