Best ResponseYou've already chosen the best response.0Never "Completed the Square"? You'll have to follow the algebra and see. Hint: \(r + s^{2} \ne (r+s)^{2}\)  generally.

Best ResponseYou've already chosen the best response.1you have to look at every single line to see where the mistake is made and even then it is confusing because they corrected in in the end

Best ResponseYou've already chosen the best response.0It's just completing the square. It's not a difficult thing. You should have this skill unless you haven't been paying attention in class.

Best ResponseYou've already chosen the best response.1we can take them step by step if you like, it really has nothing to do with completing the square, not to disagree with @tkhunny

Best ResponseYou've already chosen the best response.0Disagree, if you wish, but it is EXACTLY completing the square. That is where the Quadratic Formula comes from.

Best ResponseYou've already chosen the best response.1yes i know that, i mean this question has nothing to do with completing the square, they are only asking you to find a typo it is copy editing is all, has nothing to do with the math involved

Best ResponseYou've already chosen the best response.1it is like "find the difference between these two pictures" don't think about math, just find one line where they copied something different than the previous line

Best ResponseYou've already chosen the best response.1step 6 \[x+\frac{b}{2a}=\sqrt{\frac{c}{a}+\left(\frac{b}{2a}\right)^2}\] step 7 \[x=\frac{b}{2a}+\sqrt{\frac{c}{a}+\left(\frac{b}{\color{red}{4a}}\right)^2}\]

Best ResponseYou've already chosen the best response.1it is just a typo, has nothing whatsoever with the quadratic formula, completing the square, any math at all just a simple typo for you to find

Best ResponseYou've already chosen the best response.1what makes it worse it it was rectified in the next step, so the actual formula is correct

Best ResponseYou've already chosen the best response.0Try again. If you complete the square, and follow the process, you will detect any typo. Seriously, this is a legitimate math question. The solution is simple and more rational if you treat it so. The FIRST error is IN step 6, not after it. If you had completed the square properly, you would have seen it.
