if x = 1 then\n\n3 - 12 x 3 + 4 - 4 = 27\n\nbasically depends on what is x??\n\nor suppose it goes like this?\n\n9 - 24 x 6 + 4x - 4 = still need to know what x is...\n\nif x = 1 then the answer is -90\n\nYou really must clarify what x is...thanks!!!

3(4x+6)+7\n\nexpand first (ie multiply what is in the bracket by what is out side the bracket)\n\n= (3 times 4x + 3 times 6) +7\n=12 x + 18 + 7\n\nthen collect like terms (i.e. similar powers of x)\n\n= 12x +25

6+4x+6-3x=x\n\n12-12x= x/12x +12x\n\n12=13x\n\n12/13= x

1. square both sides: 4x-3=1296\n2. add 3 to both sides: (4x-3)+3=1296+3; 4x=1299\n3. divide by 4: (4x)/4 = 1299/4;  x=324.75

i doubt u got it right. this is how u do it:\n\nfirst u group them \n\n(x³-3x²)+(4x-12)\n\nthen simplify each binomial\n\nx²(x-3)+4(x-3)\n\nthen since (x-3) are the same on both of them u group them together\n\n(x²+4)(x-3)\n\nand there u have it

12 simply place the 1 where the x is\n\n(1+3)(1+2)\n4*3\n12

I prefer "long" multiplication but it doesn't line up as well...\n\n3x^2 + 7x - 6\n* _____x+12\n--------------------  Multiplying term by term\n_____36x^2 + 84X - 72\n3x^3 + 7x^2 - 6x\n--------------------------------  Add term by term\n3x^3 + 43x^2 + 78x - 72   <--  final answer

(4X^3 +12X^2) + (12X +36)= 4X^2(X+3) + 12(X+3)\nX+3 is common.. hence we could write...\nas (X+3)(4X^2 + 12)= 4(x^2+3)(x+3)

-4(3-x) = 2(x+6) \n-12+4X=2X+12 use distributive property\n-12+4x-2x=2x-2x+12 move the variable x onto 1 side \n-12+12+2x=12+12 isolate the variable x\n2x=24\n(2x/2)=24/2\nx=12\n\nCheater!

Your denominators are 4, 6 and 3.  The least common multiple of 4, 6 and 3 is 12, so multiply everything by 12.\n12(x-1)/4 - 12(x-2)/6 = 12(2/3)\nSimplify\n3(x-1) - 2(x-2) = 4(2)\nDistribute\n3x - 3 - 2x + 4 = 8\nCombine like terms\nx + 1 = 8\nSubtract 1 from each side\nx = 7

I got   3(x² - 5x + 4) or 3( x - 4 )( x - 1 )\n\nLet me show you my work...\n\n3( x - 2 )² - 3(x - 2) - 6\n\nSimplify\n\n3( x -2 )( x - 2 ) - 3( x- 2 ) - 6\n\nDistribute\n\n3( x² - 4x + 4) - 3x + 6 - 6\n\nDistribute and Simplify\n\n3x² - 12x + 12 - 3x\n\nSimplify\n\n3x² - 15x + 12\n\nYou can now simplify by factoring out 3\n\n3(x² - 5x + 4)\nor\n3( x - 4 )( x - 1 )

(3c-3d)(4c-4d)\n=3c*4c -3c*4d-3d*4c+3d*4d\n=12c^2 - 12cd - 12cd +12d^2\n=12c^2 - 24cd + 12d^2 (you can stop here or continue like following)\n=12 *(c^2-2cd+d^2)\n=12 *(c-d)^2\n\nJust remember: \n\n1) (A+B)(C+D) = AC + AD + BC +BD\n\n2) A^2 - 2AB + B^2 = (A-B)^2\n\nGood luck!

4 to the 3rd is 4 multiplied by itself 3 times\n\n4 to the 3rd = 4 x 4 x 4\n\n2 to the 6th = 2 x 2 x 2 x 2 x 2 x 2

OK,as the first one is already done,I am doing the rest for you\n4(2x-6)=x+2 =>8x-24=x+2  =>8x-x=2+24  =>7x=26  =>x=26/3=8 2/3  (3) 2(x+5)+1=3(x-1)+4   =>2x+10+1=3x-3+4 =>2x-3x=-3+4-10-1  => -x=-4  =>x=1  (5)x+6=4(4x-1)   =>x+6=16x-4  =>x-16x=-4-6  => -15x=-10  =>x=-10/-15=2/3 [after reducing]
