Re TY
Sry, You did not say You were wanting the formulas for solving cubic equations:
See x[2]below: Plug and Play, the value of a would simply be:
a = Answer formatted as directed.
Recommend using a Graphing calculator to find the real root
Or cubic equation Calculator to find all:
f(x)=2x^3- 6x^2+6x-7 |format ax^2 + bx^2 + cx + d
3 Roots, 2 imaginary (nearest 4 decimal places)
x is 2.3572, .3214 + 1.1754i, .3214 - 1.1754i
a = 0.3213955958512734
X[1] =
x[2] =
X[3] =
