WebbIt's not quite true that you don't know x. The question says you need to find the value of k that can make the equation true for all real values of x. You need a value of k that works for every x you can put in. So you could substitute x = 0, and get 3a = k. You could substitute x = 1, and get 2a - 2 = 1 - 11a +k. With x = a you get 0 = k - 10a 2. Webba is a constant, therefore so is lna, so produce rule would yield lna.dx/dx + x.d (lna)/dx = lna + 0. Ah okay, so if I just think of it as ln (a).x instead of xlna then I should remember that …
