This is a great question to illustrate the calculus principle of differentiation (i.e. differential of y with respect to x)\n\nx2-x+m=0 ---- eqn. 1\nx3-x2+6x+24=0 ---- eqn. 2\n\nSince both are = 0, for eqn. 1 = eqn. 2, we have:\n=> x2-x+m = x3-x2+6x+24\n=> x3-2x2+7x+24-m=0\n=> x3=2x2-7x+m-24 ---- eqn. 3\n\nLet y = x3. Therefore, in eqn. 3, we have:\n=> y = 2x2-7x+m-24  ---- eqn. 4\n\nTaking the differential of y w.r.t. x (i.e. dy/dx), we have RHS (right hand side):\n=> dy/dx = 4x-7 (since m and 24 are integers, they 'disappear' as they do not vary with x) ---- eqn. 5\n\nBut from eqn. 4, we know y = x3. Therefore, LHS(left hand side):\n=> dy/dx = 3x2 ---- eqn. 6\n\nSince eqn. 5 = RHS and eqn. 6 = LHS, we have:\n3x2 = 4x-7\n\n3x2 -4x +7 = 0  (in the form of ax2+bx+c=0)\n\nTechnically, there is no real solution for x (perhaps you have input a wrong sign for one of the 2 equations in your question?) Anyhow, proceeding, using general formula for quadratic equations where x = 1/2 (-b +/- sq.rt of [b2-4ac]), then:\n=> x = 1/2( 4 +/- sq. rt of (-80))\n     = 2 +/- sq. rt. of (-20)\n    = 2 +/- sq.rt. of 20 i (where i = sq. rt. of -1)\n\nAbove topic is calculus topic on REAL AND IMAGINARY numbers.\n\nTherefore, subbing values for x into eqn. 1, you will get the 2 values for m.\n\n\nOR alternatively:\nBy trial and error on eqn. 2, we get:\n=> x3-x2+6x+24 = (x+2) (x2-3x+12)\n          \nSolve values for x = -2, 1.5 +/- sq.rt. of 39 i (where i = sq. rt. of -1)\n\nSubstitute values for x into eqn. 1 and you will get values for m.

There are precisely three answers:\nABCDEFGHJ\n267835149\n267953148\n678413259\n\n(slightly offtopic, how can you spend 30 minutes on a question that was asked 8 minutes before you answered ;) Just kidding.)\n\nTry each one and check that it works :) Unless you didn't mean  F(G*H) as F*(G*H), and meant the digit F followed by the answer G*H.. in which case I'll try solving it again. If you did mean it like that, there is indeed a unique answer:\n\n589736142\n\nAhha, third question change. Now it becomes 256973148.

Iguess no one knows the right answer.

there is no answer becuase it is impossible to divide by 0

I agree with Mike, do your math homework.  Everyone would love to hang around someone who knows how to do math.

jf rodrigues is correct to add 65. The others are putting in parentheses where none appear in the problem. They end up subtracting 65 instead of adding, and are getting answers that are too low by 130.\n\nThe wrong answers are obtained by people subtracting and even multiplying(!) 65 when they should be adding it.

12.\n\nEverytime you see the question...  What number is both a factor and a muliple of X, X will be the answer.

a + 4a where a = 2 ?\n\nif so, then...\n\n2 + (4)2\n\n2 + 8\n\n10\n\nThe answer is 10.

4+4 will = 1\n\nThe logic is the answers are going down from five only in odd numbers thus the answer is 1.

no  one can give the corrrect answer  4 this question

isn't it to add pairs of mumbers like (1+100) (2+99) (3+98).......(50+51)\n\nall the answers are 101, and there are 50 answers\n\nso 101 x 50 = 5050

do you really want someone else to think for you?\nhmmm...well then...\nhere it goes...\n1. look in your math book...there are examples of how to do this problem...\n2. same answer as above!!!\n#3... same...\n\n#4!!!! remember Einstein solved "un-solve able" problems!!!

Pretty slick, RED\n\nYou came on pretending that "someone else" had a problem and even gave out a wrong answer on purpose.  Clever!\n\nI can see through that, you just wanted people to give you the right answer without giving you the whole "Do your own homework" speech.\n\nNice! Score one for you.  Unless, of course, I am giving waaaay too much credit for such an ingenious plan.  In which case, x=2, not 24.

Yep, someone can.\n\nDO YOUR OWN HOMEWORK.

half it then times it by 2! that will give u the answer
