3x(2x + 1) over (2x - 1)(2x + 1) Cancel out the 2x + 1 Answer: 3x/2x - 1
2x+12-3x = 5 2x-3x = 5-12 x = -7
2x + 3x = 5x
2x-3x = -1
No. 3x plus 2x = 5x. 3x multiplied by 2x = 6x²
As written, that's -x - 2, which is in its simplest form. 2x^2 - 3x - 2 = (2x + 1)(x - 2)
3x(2x + 1) over (2x - 1)(2x + 1) Cancel out the 2x + 1 Answer: 3x/2x - 1
3/x2
2x+12-3x = 5 2x-3x = 5-12 x = -7
If 3X - 4 ------ = 0 1-2X-4 So 3X - 4 ----- = 0 [ x (2X-3) ] 2X-3 3X-4 = 2X-3 [ -2X ] X - 4 = -3 [ +4 ] X= 1
3x - 2 is in its simplest form.
x2/(3x2 - 5x - 2) - [2x/ (3x + 1)][1/(x - 2)] = x2/(3x2 - 6x + x - 2) - 2x/(3x + 1)(x - 2) = x2/[3x(x - 2) + (x - 2)] - 2x/(3x + 1)(x - 2) = x2/(3x + 1)(x - 2) - 2x/(3x + 1)(x - 2) = (x2 - 2x)/(3x + 1)(x - 2) = x(x - 2)/(3x + 1)(x - 2) = x/(3x + 1)
2x + 3x = 5x.
2x - 3x = -x
2x + 3x = 5x
2x-3x = -1
3x + 2x - 8x + 2x = -x
