4x-1=2x+1
(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
(2x + 1)(2x + 1) or (2x + 1)2
(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4
If: 1-2x-5 = 4x+2 Then: -2x-4x = 2-1+5 And: -6x = 6 So: x = -1
4x-1=2x+1
(2x-1)(2x-1) = 4x^2 -4x + 1
4x2-4x+1 = (2x-1)(2x-1)
8x2 + 2x - 1 = 8x2 + 4x - 2x - 1 = 4x(2x + 1) - 1(2x + 1) = (4x - 1)(2x + 1)
(2x + 1)(2x + 1) or (2x + 1)2 so x = -0.5
2x + 2 = 4x -1 2x = 3 x = 1.5
(2x + 1)(2x + 1) or (2x + 1)2
4x + 1 = 2x + 5 Subtract '1' frp, bpth sides Hence 4x = 2x + 4 Subtract '2x' from botbh sides 2x = 4 Divide both sides by '2' x = 2 The answer!!!!!!
(4 + 2x) - (-2x + 1) = 13 + 6 4 + 2x + 2x -1 = 19 4x +3 = 19 4x = 19 - 3 4x = 16 therefore x = 16/4 x = 4
Assuming there are no parentheses:2 times X - 1 + 4X - 6 + 2X =2X - 1 + 4X - 6 + 2X =2X + 4X + 2X - 1 - 6 =8X - 1 - 6 =8X - 7
If: 1-2x-5 = 4x+2 Then: -2x-4x = 2-1+5 And: -6x = 6 So: x = -1
4x2 + 8x + 4 = 4 (x2 + 2x + 1) = 4 (x + 1)2
