Kua tāruatia ki te papatopenga
\left(x^{2}-20x\right)\left(x-39\right)
Whakamahia te āhuatanga tohatoha hei whakarea te x ki te x-20.
x^{3}-39x^{2}-20x^{2}+780x
Me hoatu te āhuatanga tohatoha mā te whakarea ia tau o x^{2}-20x ki ia tau o x-39.
x^{3}-59x^{2}+780x
Pahekotia te -39x^{2} me -20x^{2}, ka -59x^{2}.
