Best ResponseYou've already chosen the best response.0oh. okay. Then you really shouldn't be doing this sort of problem. Let me post a couple of links so that you can first learn some basic algebra and then come back here.

Best ResponseYou've already chosen the best response.0oh. You really should learn how to do these questions. They're not hard ^^ Here's your answer with explanations: 12x²  1 = x [[move everything to one side and get the equation into the general form ax²+bx+c =0]] 12x² + x  1 = 0 [[You're looking for 2 numbers, m and n, with the conditions that m+n = b and mn = ac. So in this case, two numbers that add to be 1 and multiply to be 12. 4 and 3 work, so split x into 4x and 3x]] 12x² + 4x  3x  1 = 0 [[Factorize by grouping in pairs]] 4x(3x + 1)  (3x + 1) = 0 [[Factorise (3x+1) out]] (4x  1)(3x + 1) = 0 [[Solve]] x = 1/4 or x = 1/3
