What is 2X plus X plus 5 plus 3X-6?
2x+x+5+3x-6=6x-1
What are the 2 solutions to the equation x plus 3 divided by 3x plus 1 equals 2x-1 divided by 3-2x?
Cross-multiplying gives: (x + 3)(3 - 2x) = (3x + 1)(2x - 1) ie -2x2 - 3x + 9 = 6x2 - x - 1 add 2x2 to each side: -3x + 9 = 8x2 - x - 1 add 3x to each side: 9 = 8x2 + 2x - 1 subtract 9 from each side: 8x2 + 2x - 10 = 0 divide by 2: 4x2 + x - 5 = 0 Factors are: (4x + 5)(x - 1) x = -1.25 or 1
What is 3x plus 1 times 2x plus 4?
(3x+1)(2x+4) = 6x2+4+2x+12x = 6x2+14x+4
How do you Factorise this 12x square 7x plus 1?
12x2 + 7x + 1 = 12x2 + 3x + 4x + 1 = 3x*(4x + 1) + 1*(4x + 1) = (4x + 1)*(3x + 1)
What does 3x plus x equal?
3x+x=4x. The 3x is just an easier way of stating x+x+x, and then you would just count the x's up like normal to create a total. You can also do this with larger numbers. For example, if you have 100x+500x, you would still add the numbers together to create a total of 600x. As long as the variables (x, in this case) are the same in the numbers you're adding (i.e., you can't add 3x+y together) you can just add the numbers to create your total.
What does (3x plus or minus 1 )2 equal Does It equal (3x plus 1)(3x-1)?
I think you mean (3x ± 1)^2 = (3x+1)(3x-1)?
What is 3x plus 4y plus 10 plus 12x plusy plus 1 simplified?

How do you factor 9x squared plus 6x plus 1?
9x2 + 6x + 1 = 9x2 + 3x + 3x + 1 = 3x(3x + 1) + 1(3x + 1) = (3x + 1)(3x + 1) or (3x +1)2
What is 3x plus 1 plus 10?
3x + 11
How do you factor -9x3-3x2 plus 3x plus 1?
If that's -9x^3 - 3x^2 + 3x + 1, that factors to (1 - 3x^2)(1 + 3x)
What is 2x2 plus 3x plus 1 factored?
2x2 + 3x + 1 = (x + 1)(2x + 1)
