8x^2y\n\nas long as the x's and the y's are the same in both terms, you can just add them up...\n\nboth terms have x^2 and both terms have y and no other variables, so just add them up\n \n(3+5)x^2y = 8x^2y

Like terms have the same variable (or have no variable).  In  this expression you have two sets of like terms: Those with x, and those with y\nThose with x: 5x, -x, 2x\nAdd the coefficients:  (5-1+2)x = 6x\n\nThose with y: 7y, -2y\nAdd the coefficients: (7-2)y = 5y\n\n6x+5y  is the answer.\n\nHope this helps.

x³y - 3x²y - 10xy --- Take x and y out of each term...\nxy(x² -3x - 10) --- Factor the x² - 3x - 10\nxy(x - 5)(x + 2)\n\n*Note: To show exponents, such as x², use the ^ key (such as x^2). This expression looks like you basiclly wrote:\n3xy - 6xy - 10xy

Multiply it out...\n2y+6y+24x-24y-6x\nThen combine\n-16y+18x OR\n18x-16y

You group all like terms together so it would be \n-5x+5x-3y+y-9z+8z\n-5x+5x that = 0\n-3y+y=-2y\n-9z+8z=-z\nSo you bring it all together and you have\n-z-2y

2x/x^2 - 5x + 6 + 4/x - 2\n\nFirst we will simplify\n2x/x^2\n\nThe x on the top crosses out and the x^2 on the bottom becomes x.  We end up with 2/x.\n\n2/x - 5x + 6 + 4/x - 2\n\nNow we combine like terms.  All of the terms with just numbers will be added together.  Everything with something over x will be combined. \n\n(2/x + 4/x) - 5x + (6 - 2)\n\nWe have 6/x - 5x + 4\n\nNothing else can be combined so it is now in simplest form.
