Cubic function

α>β>γ,α-β>β-γ,α-β<β-γ,α-β=β-γ f(x) = ( x +α )( ax2+bx+c ) = ( ax2+bx+c )( x+γ ) = ax3+(b+aα)x2+(c+bα)x+cα = ax3+bx2+cx+d T.theodor 2022.6.26

cubic function

cubic function y = ax3+bx2+cx+d y = (αx+β)(γx+δ)(εx+ζ) = (x--b-√b2 − 4ac/2a)(x--b+√b2 − 4ac/2a)(εx+ζ) = (αx+β)(x--b-√b2 − 4ac/2a)(x--b+√b2 − 4ac/2a) T.theodor 2022.6.26
