Разложите множители на многочлен 2n(во второй степени)-3an-10n+15n (5+n)(2n-3n) (2n−5)(n+3a) (3a−n)(5−2n) (2n+3a)(n+5) (5−n)(3a−2n)

2n^2-3an-10n+15n=2n^2-3an+5n

(5+n)(2n-3n)=10n-15n+2n^2-3n^2=-5n-n^2=-(5n+n^2)

(2n−5)(n+3a)=2n^2+6an-5n-15a

(3a−n)(5−2n)=15a-6an-5n+10n^2

(2n+3a)(n+5)=2n^2+10n+3an+15a

(5−n)(3a−2n)=15a-10n-3an+6n^2
