anyone know how to do this (X-a)x(X-b)...x(X-z) i do?

One of the factors will be x-x=0.\nSo, the answer is 0.\nThis is because 0 times any number is 0.

isolate the variable.\n\nfirst subtract 3 from both sides.\n2x=6\n\nisolate the variable further.  Divide each side by 2\nx=3

[2x/(x+3)(x-3)]*[(x-3)/4(x)]\ncancelling 2 and x-3 we will get\n=x/(x+3)2(x)\nsimplify we will get\n=x/(2x^2+6x)

(2x-9)(2x+9)\n\na guess... its been a long time since I did that stuff

You have to isolate the "X"\n\n1. Subtract  9 from both sides\n2. Then divide both sides by 5

x^2-x-6>0\nor, x^2-3x+2x-6>0\nor, x(x-3)+2(x-3)>0\nor, (x-3)(x+2)>0\nor x>3 and x<2\n\nhope this helps :)

x + y + z = t\n\nx +x% + y + y% + z + z% =\n[(100 + 1)( x + y + z)]% =\n101t% = t + t%. So\nx +x% + y + y% + z + z% = = t + t% or\nx% + y% + z% = t%

yes. take out an x \nyou answer should be x(x+3)

1-x = -(x-1)\nx^3 - 1 = (x-1)(x^2+x+1)\nAnswer: -(x-1)(x^2+x+1)

a/bX + c = d\n\nfirst add -c to both sides\n=> a/bX + c-c = d-c\n=> a/bX = d-c\n\nNext time multiply b on both sides\n=> b * a/bX = (d-c) * b\n=> aX = b(d-c)\n\nAnd last divide both sides by a\n=> X = b(d-c)/a\n\nin this case:\n\nX = -4

if u meant make x the subjct then tis is how u wd go abt it.\n\na^2 - ax = b^2 - bx\nax-bx=a^2 - b^2\nx(a-b)= a^2-b^2\nx        =(a^2-b^2)/(a-b)\nx        =[(a-b)(a+b)]/(a-b)    (using difference of two squares)\nx        =a+b

You have to first eliminate one variable from two of the equations which would leave two equations with two variables.\nThen eliminate one of those two variables to get one value.  Plug this in to get a second value; plug these in to get the third.\n\nFor example in your problem b, if you multiply the second row by -1 and add it to the first row, that would eliminate z\n\n(2x - 1y = 1)\n\nThen divide the third row by 2 and add it to the (original) first row, which also eliminates z\n\n(20x - 4y = 16)\n\nNow take those 2 rows, eliminate either x or y, and start plugging in

a (x+y) + b (x*y) = z

You will want to isolate the variable (many times it is 'x'). First you will add or subtract from each side. Then divide. For example:\n5x+4=19, subtract 4 from each side giving 5x=15. Then divide by 5 giving x=3. I hope this helps.
