# Cardano solves x^3 +6x=20
#### Sorry, this page requires a Java-compatible web browser.
Choose u and v so that
u^3 - v^3 = 20 and
u v = 2
Let x = u - v
u^3 - v^3 = 20 = x^3 + 3xv^2 + 3vx^2
x^3 = u^3 - 3vu^2 + 3uv^2 - v^3
so 3vu^2 - 3uv^2 = 3xv^2 + 3vx^2 = 3xv(v+x) = 3xvu = 6x
Thus x^3 +6x = u^3 - v^3 = 20 | HuggingFaceTB/finemath | |

Thus,
$k = \pm \left(r - 1\right)$
#### Explanation:
$r = 1 - k \cos t$
Here, $\cos t$ can change from -1 to 1
For $\cos t = - 1$
$r = 1 - k \left(- 1\right)$
$r = 1 + k$
Solving for k
$k = r - 1$
for $\cos t = 1$
$r = 1 - k \left(1\right)$
$r = 1 - k$
Solving for k
$k = 1 - r$
