Problem: solve a logarithmic equation
Equation to solve: ln(x+4)+ln(2*x+3)-ln(1-2*x) = 0
Interval for roots: [-5 ; 5]
Solution:
DeadLine can solve logarithmic equations instantly, providing the equation graph and the roots.
Number of roots found : 1
x1 = -1
In fact, the logarithmic equation could be easily transformed in: (x+4)(2x+3)=1-2x, but the two equations are not equivalent. The second equation has two roots: -5.5 and -1, while the logarithmic equation has only one root, that is -1.
