Hello, im revising eigenvalues in matrices and ive come across a part where i need to factorise the following quadratic equation; let lander = x(adsbygoogle = window.adsbygoogle || []).push({});

36-36x+11x^2-x^3 = 0

I know that the answer is (x-2)(-x^2+9x-18), but i dont know how he got to it.

Ive look through google but i cant find any information on quadratics of this type.

Thanks in advance
