2x - 5 - 4x + 8= 2x - 4x - 5 + 8= -2x + 3
X= -8
3x-5
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
(2x - 8)(-4x + 4) = -8x2 + 40x - 32
2x - 5 - 4x + 8= 2x - 4x - 5 + 8= -2x + 3
Simplify 4x + 3 = 2x + 8 2x = 5 x =2½
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
X= -8
3x-5
It is: 11-6x as a simplified expression
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
The derivative of 2x2 + 4x + 8 is 4x+4.
(2x - 8)(-4x + 4) = -8x2 + 40x - 32
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13
Lets simplify the above given equation : -8 plus 6(-x - 3) plus 4x simplified as : -8-6x -18 +4x =-2x -26 . =-2(x+13).
2x/3 = 8 + 4x2x = 24 + 12x-24 = 10x-2.4 = x
