Solve the equation:
(t-4)^6-11(t-4)^3+28=0
-----
This is a quadratic equation with variable (t-4)^3
----
Let W = (t-4)^3 ; then you get:
W^2 - 11W + 28 = 0
Factor::
(W-7)(W-4) = 0
W = 7 or W = 4
------
Solve for "t"::
(t-4)^3 = 7 or (t-4)^3 = 4
t = 7^(1/3) + 4 or t = 4^(1/3) + 4

Do you see this is in quadratic form?

Let ------------even better, let . You would use this to first solve for v.
