Best ResponseYou've already chosen the best response.0then...\[\ln (x ^{2}2x)=\ln 8\]

Best ResponseYou've already chosen the best response.0then drop the ln... \[x^{2}2x=8\]

Best ResponseYou've already chosen the best response.0well you e^ both sides. That's how the ln cancel. But then you are left with a quadratic equation

Best ResponseYou've already chosen the best response.0split the two, \[x^{2}=8\] and \[2x=8\]

Best ResponseYou've already chosen the best response.2Compare your quadratic equation with \(ax^2+bx+c=0\) find a,b,c then the two roots of x are: \(\huge{x=\frac{b \pm \sqrt{b^24ac}}{2a}}\)

Best ResponseYou've already chosen the best response.0okay gimme a second to work that out.

Best ResponseYou've already chosen the best response.0*** and need to remember to check for valid values of x. if you are taking ln(x) and ln(x2) what can't x be?

Best ResponseYou've already chosen the best response.0You can always complete the square. That's another way of solving this without the long work of using the quadratic

Best ResponseYou've already chosen the best response.0whats finishing the square? Sounds like a shortcut I was denied...

Best ResponseYou've already chosen the best response.0... or just factor? \[x^22x8=0=(x?)(x+?)\]

Best ResponseYou've already chosen the best response.0\[x^2−2x−8=0=(x−A)(x+B)\\ A*B=8\\ A+B=2\] Find A and B

Best ResponseYou've already chosen the best response.0You have a system of question where you can simply plug in one equation to another if you can't see it right away. Then solve for the missing variable.

Best ResponseYou've already chosen the best response.2so what are 2 values of x u got ?

natnatwebb

Best ResponseYou've already chosen the best response.0ten solving its 4 and 2

natnatwebb

Best ResponseYou've already chosen the best response.0and 2 would be extraneous

gohangoku58

Best ResponseYou've already chosen the best response.2but can x be 2 ?? think ....

gohangoku58

Best ResponseYou've already chosen the best response.2yes, so x is only = ?
