They will converge after x miles  \nX=200t =500(t-2)\n300t = 1000\nt= 3.33 hour\nx= 200 *3.33 = 666.66 mile

Well, the sum of two terms thing is stupid, but oh well. (You can immediatly make it (x-5)(x-9))\nx^2-9x-5x+45=x(x-9)-5(x-9) --> (x-5)(x-9)

u jammed the equation together.\ndo u mean\n6x^3 + ( 6/x - 2 * x^2 - x/3x2 - 3x + 3)\nits really hard to see ur question. can u write it out with spaces...\nhurry up i am waiting... lol

If m equals to 7\n3 (m-5)+1 = 2(m+1)-9\n3m-15+1 = 2m+2-9\n3m-14 = 2m-7 (add 7 to both side)\n3m-7 = 2m (subract 3m from both side)\n-7 = -1m\n-7 = m

COS_STUDYGROUP is COMPLETELY WRONG.  (2-7x)^2 == 4+49x^2, please don't get confused about that!\n\nWhile the first user above me is completely correct. I'd like to go a step further and explain how he arrived at that solution.  See that number in front of the x squared?  It should look familiar, if you take the square root of it you get an even 7.  That is how he got to 2 7x's.  The 4 when square rooted becomes a 2.  So now we have a 2 and a 7x in each set of parentheses.  Since the x squared is negative that means that the signs must mismatch so one + and one -.\n\nSo we arrive at the equation (-7x + 2)(7x + 2) or (2 - 7x)(2 + 7x) .... I was always taught the number with the x goes first.

This is not presented as an equation, so the goal appears to be to combine the rational expression --> x+10 \nThat's all you can do with the question as it is written.

Nobody can help you because it's false.\n\nLet a1 = 1, a2 = 4, b1 = 2, b2 = 3, and n = 7\nThen a1 + a2 = 5, b1 + b2 = 5\nBut a1*a2 = 4, while b1*b2 = 6.\n\nYou are talking about modular arithmetic, right?

For algebra, you have to remember that you can only add like terms.\n\nSo first, forget about the parentheses, since you're not doign anything to what's in the parentheses (for example, you aren't squaring it or multiplying it all by two).  Then rewrite your equation as:\nx^2 + 2x +5 + 3x^2 -3x +1\n\nNow gather all like terms. What that means, is put all the numbers that contain an "x^2" together. And put all the numbers that contain just an x together, or no x at all, and so on.\n\nso you have:\nx^2 + 3x^2    + 2x -3x   +5 +1\nthen you can add like terms\n4x^2   -1x  +6

umm..are you missing an equals sign somewhere or am i really dumb? how do you figure out what x is unless you have both sides of the equation?

Yuo can't solve this.Because it is a formula and not an equation..If u assign some value equal to this formula such as 0 u have the solution.

by any chance is this a question from your maths homework? lol :D\n\nI cant work it out myself because to put it simple, im crap at maths.

(12x^2 +16x) - (12x-7)- (4x-5)\n12x^2 +16x -12x +7 -4x +5\n\n12x^2+12\n\nthat is what I got....\nI think you might be able to put 12 on the other side of the = sign and turn it into 12x^2 = -12 and then since both sides have 12 in common you can divide both sides by 12 and you will have x^2 = -1 then you can add 1 to both sides and you will have x^2 +1 but I think I'm getting off track by that point....it's been a while since I had to do this stuff.

guess if algebra, it would go like this 2 minus make a plus \nso 14- - (+) 14=28/14= 2
