f(x)=x3-7x+6 Since (a + b + c + d = 0), then f(1) = 0 --> one factor if (x - 1).

After division -->

f(x)=(x-1)(x2f2+x-6). The trinomial in parentheses can be factored.

Neurogenesis is the process by which new neurons are created and developed in the brain. The new neurons are created by neural stem cells and it happens in almost all species of animals. Neurogenesis is effectual during embryonic development and completely through adult life in different organisms.
