Question

Разложите на множители квадратный трёхчлен

Answer 1

a^2-13a+22=

=a^2-2a-11a+22=

=a*(a-2)-11(a-2)=

=(a-11)*(a-2)

==========================================================

-b^2+2b+24=

=-b^2+6b-4b+24=

=-b*(b-6)-4(b-6)=

=(-b-4)*(b-6)

==========================================================

100c^2-50c+6=

=2(50c^2-25c+3)=

=2(50c^2-10c-15c+3)=

=2(10c*(5c-1)-3(5c-1))=

=2(10c-3)*(5c-1)
