Math...
Find the exhaustive set of values of 'a' such that log(x²+2ax)=log(8x-6a-3) has only one solution for x.
Well I found this in chat during livestream and wish to know the answer. I m a 11th grader so if it's in 12th ka concept, do let me know.
I could just think of converting it into a quadratic then found a=1 or 13, am i right?

yea this works!
btw when a = 13
accha nvm yea x = -9 :)
yes correct
also
just put a in the equation again, find values of the individual quadratics at the roots and check if they lie in the domain of log
because you don't want negative values
pretty sure one of the values of a will get rejected
okay got it
thnku
indeed, a cannot be 13
