By: VirtualNerd. on 09 Sep 10, 01:20:00 That? is a really great and thought provoking question. Thanks for asking it. The short answer is yes! If we had 2x^3+4x, then 4 is the coefficient for the x^1 term, and 2 is the coefficient for the x^3 term. So, the coefficient is linked to the variable and the power. I Now what if we had 2x^3+4x+5? Well, 5 is really 5*x^0, because x^0=1. So, 5 is the coefficient of the x^0 term! That argument works for any standalone number. Does that make sense :) they are? separate By: robbstews. on 03 Aug 10, 23:04:32 they are? separate Thanks for the ... By: VirtualNerd. on 22 Jul 10, 18:07:31 Thanks for the question! 6 is the coefficient for 'a', 1 is the coefficient for 'b', and 2 is the coefficient for x^2*y, so they are all separate coefficients.

By: finbomartini. on 22 Jul 10, 17:45:51 So 612 is the coefficient of the equation? Or 6, 1 and 2? are all separate coefficients?

By: 212jbh. on 15 May 11, 20:35:36 I found? an easier solution to my problem: a problem has 'double roots' when it is a perfect square: (x-5)(x-5)=0. This means that it just touches the x axis without going below to the negative Y axis, thus it can't come back up and have a second root. Anyone who has the same question can try it by graphing a perfect square. If it never touches the x axis then it has no real roots Actually this is ... By: dalcde. on 31 Dec 10, 13:22:42 Actually this is the reason (I think): x^2+2x+1 has the root -1. To obtain the root, we factorise the equation into (x+1)(x+1). The first root comes from the first factor (x+1) which has to equal? 0. The second root comes from the second factor. There are two roots from two factors, but they just happen to be the same. Perhaps this is ... By: dalcde. on 31 Dec 10, 13:22:38 Perhaps this is what happened: some mathematician found out that a polynomial of degree n has n roots.
