x(x - 19)(x - 1)
They touch each other at (0, 100) on the x and y axis.
20X2 + 3010(2X2 + 3)============That's as much factoring as can be done here.
5x2 + 20x = 5x (x + 4)
ça ne marche pas...
x(x - 19)(x - 1)
20x3 - 70x2 + 60x = 10x(2x2 - 7x + 6) = 10x(2x - 3)(x - 2).
They touch each other at (0, 100) on the x and y axis.
(2x - 5)(2x - 5) or (2x - 5) squared
20X2 + 3010(2X2 + 3)============That's as much factoring as can be done here.
4x2+20x+25 (2x+5)^2
5x2 + 20x = 0 5x(x + 4) = 0 x = 0 and -4
(2x + 5)(2x + 5)
(x - 8)(3x + 4)
5(x + 3)(x + 1)
5x2 + 20x = 5x (x + 4)
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)
