Sqrt (5-6*x)*ln(4*sqr(x)-sqr(a))=sqrt(5-6*x)*ln(2*x+a)
Find all possible a when an equation has only one possible solution.

Avalance789 said:Sorry, I have confused you. Should be written like
sqrt (5-6x)*ln(4x^2-a^2)=sqrt(5-6x)*ln(2x+a)So sorry
Mark, seems to me that above easily/instantly simplifies to:MarkFL said:Okay, so the equation is:
\(\displaystyle \sqrt{5-6x}\ln\left(4x^2-a^2\right)=\sqrt{5-6x}\ln\left(2x+a\right)\)
Wilmer said:Mark, seems to me that above easily/instantly simplifies to:
4x^2 - a^2 = 2x + a
No?
Avalance789 said:Just tell me if a<2/3 is correct answer. I will be happiest person on Earth, guys
Wilmer said:4x^2 - a^2 = 2x + a
Yes...but this was the OP's:greg1313 said:$$4x^2-a^2=(2x+a)(2x-a)$$
Only if you recite the Hooooooly Rosary twice !greg1313 said:Ah, pardon me.
The equation represents a relationship between the square root of the difference between 5 and 6 times x, multiplied by the natural logarithm of the square root of 4 times the square root of x minus the square root of a, and the square root of the difference between 5 and 6 times x, multiplied by the natural logarithm of 2 times x plus a.
The variables in this equation are x and a. x represents a number or value and a represents another number or value. They can be any real numbers that satisfy the equation.
This equation is a nonlinear equation and can be solved using various methods such as substitution, elimination, or graphical methods. It can also be solved using numerical methods such as Newton's method or the bisection method.
The natural logarithm, represented by ln, is a mathematical function that shows the relationship between a number and the exponential value of that number. In this equation, the natural logarithm is used to represent the relationship between the two sides of the equation and to find the values of x and a that satisfy the equation.
Yes, there are some restrictions on the values of x and a in this equation. For example, the values inside the square root cannot be negative, so x must be greater than or equal to 5/6 and a must be greater than or equal to 0. Additionally, the values inside the natural logarithm cannot be negative, so 2x+a must be greater than 0.
