It is 2x + 5. The value of this expression will depend on the value of x: each different value of x will give a different value for the expression.
-3
5x
2x+x+5+3x-6=6x-1
If: 2x = x+5 Then: x = 5
2x-3 = x+5 2x-x = 8 x = 8
8x2 + 15 + 26x = 8x2 + 26x + 15 = 8x2 + 20x + 6x + 15 = 4x(2x + 5) + 3(2x + 5) = (2x + 5)(4x + 3)
The factors of 5 are 1 and 5. 12 = 2 x 5 + 2 x 1, therefore: 4x2 +12x +5 = (2x + 1)(2x + 5)
6 + 2x + 5 = 11 + 2x
4x3+10x2+2x+5= (2x+5)(2x2+1)
4x2 + 12x + 5 = 4x2 + 2x + 10x + 5 = 2x(2x+1) + 5(2x+1) = (2x+1)(2x+5)
(2x+5)(2x+5)
2x
(2x+5)(2x+1)
(x + 1)(2x + 5)
4x + 1 = 2x + 5 4x + 1 - 2x = 2x + 5 - 2x 2x + 1 = 5 2x + 1 - 1 = 5 - 1 2x = 4 2x/2 = 4/2 x = 2
-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.
3x+5 = 2x+13 3x-2x = 13-5 x = 8
4x2 + 12x + 5 = (2x + 1)(2x + 5).
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
