11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
x(x - 19)(x - 1)
Divide all terms by 2 and it can then be factored to (2x+1)(5x+2)
They touch each other at (0, 100) on the x and y axis.
20x2 - 3x + 10 does not have any real factors.
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
x(x - 19)(x - 1)
x=-1
20x3 - 70x2 + 60x = 10x(2x2 - 7x + 6) = 10x(2x - 3)(x - 2).
x2 + 9x2 = 10x2
5x2 + 20x = 0 5x(x + 4) = 0 x = 0 and -4
Divide all terms by 2 and it can then be factored to (2x+1)(5x+2)
The graphs of the two equations will intersect when x² + 20x + 100 = y = x² - 20x + 100 Subtracting x² +100 from both sides you get 20x = -20x that will only be true when x = 0. At x = 0, y = 100 for both equations - so the point of contact would be (0,100)
(2x + 5)(2x + 5)
(x - 8)(3x + 4)
50x squared equals 20x-2 equals zero is not possible, for 20x-2 = 0 --> x = 1/10 While 50x2 = 0 means that x should be zero. So either 50x2 =/ 20x-2 or 20x-2 =/ 0
22x is the writing speed of the DVD writer . its the speed at which the data is burnt on the DVD. its much faster than 16x,18x,20x
