SolveByWritingAnExponentAsAPowerOfAShiftedLinear​(AngouriMath.​Entity,​AngouriMath.​Entity.​Variable,​System.​Boolean)

An exponential of a polynomial of degree 3 to 12 written expanded where it is a multiple of a power of one shifted
linear and a constant, written so: a^3 + 3 a^2 b x + 3 a b^2 x^2 + b^3 x^3 is b^3 (x + a/b)^3. With
p the leading coefficient and s = p_(n - 1)/(n p), the polynomial less p (x + s)^n is a constant
exactly where each lower coefficient is p C(n, j) s^(n - j), and the integrand with the exponent written so
is the rule's below for a polynomial beside a function of a shifted linear. Rubi's 2.3.
