Steps to solve:

5x² = 15x

~Subtract 15x to both sides

5x² - 15x = 15x - 15x

~Simplify

5x² - 15x = 0

~Factor left side

5x(x - 3) = 0

~Factors equal 0

5x = 0 and x - 3 = 0

___________

~Simplify 5x = 0

5x/5 = 0/5

x = 0

~Simplify x - 3 = 0

x - 3 + 3 = 0 + 3

x = 3

___________

Thus, the correct answer is 0, 3.

Logx - logx-1^2=2log(x-1)

myrzilka [38]

Answer:

x is approximately 2.220744

Step-by-step explanation:

This can be simplified a little using properties of logarithms, and then solve it by graphing:

$log(x)-log(x-1)^2=2\,log(x-1)\\log(x)-2\,log(x-1)=2\,log(x-1)\\log(x)=4\,log(x-1)$

So we use a graphing tool to find the intersection point of the graph of $log(x)$ , and the graph of $4\,log(x-1)$

Please see attached image for the graph and solution.

The value of x is approximately 2.220744
