# Solving a quartic equation
I'm attempting to rearrange an equation from an answer on the Mathematics StackExchange.
The answer given is this equation:
$$L^2 = (-ab(t)+p)^2-\left(\frac{(-ab(t)+p).(cd(t)-ab(t))}{(cd(t)-ab(t))^2}(cd(t)-ab(t))\right)^2$$

# Dihedral Groups
The dihedral group Dn or Dih(2n) is of order 2n. It is the symmetry group of the regular n-gon.
(Some denote this group D2n because its order is 2n, but I prefer Dn - after all, one doesn't denote the symmetric group Sn by Sn! - nor J1 by J175560. On the other hand, Dih(2n) is fine as there's no conf... | {} |

# How do you solve \frac { w - 3} { 3} = \frac { 2} { 5}?
May 14, 2017
$w = \frac{21}{5} = 4.2$
#### Explanation:
Solve: $\frac{w - 3}{3} = \frac{2}{5}$
We can cross-multiply:
$5 \left(w - 3\right) = 2 \left(3\right)$
Now, we can use the distributive property to distribute the 5:
$5 w - 15 = 6$
We can add $15$ t... | {} |
