The verb 'berücksichtigen' (to consider/take into account) is derived from the noun 'die Rücksicht' (consideration). 'Rücksicht nehmen' means to think of others or of certain circumstances. 'Berücksichtigen' is the verbal form of actively including this circumstance in an action.
Ein guter Planer berücksichtigt alle möglichen Probleme.
A good planner considers all possible problems.
'Berücksichtigen' is an inseparable verb because it begins with 'be-'. The prefix remains firmly attached to the verb stem in all conjugations and sentence forms.
Er hat meine Wünsche bei der Planung nicht berücksichtigt.
He did not consider my wishes in the planning.
'Berücksichtigen' is a transitive verb and always requires an accusative object. This object is the thing or circumstance that is included in the considerations.
Wir müssen die neuen Informationen berücksichtigen.
We have to consider the new information.
This verb is often combined with abstract nouns such as 'Faktoren' (factors), 'Aspekte' (aspects), 'Umstände' (circumstances), 'Bedürfnisse' (needs), or 'Interessen' (interests).
Bei der Entscheidung müssen die Interessen aller Mitarbeiter berücksichtigt werden.
The interests of all employees must be considered in the decision.

'Rücksicht nehmen auf' and 'berücksichtigen' both mean that you do not ignore something, but include it in your behavior or planning. 'Rücksicht nehmen auf' is used especially for people, their feelings, needs, or problems. It sounds more personal. 'berücksichtigen' is more general and fits well with facts, rules, costs, weather, or dates. A simple difference is: you often take other people into consideration; you consider factors.

Bei der Planung berücksichtigt sie die Arbeitszeiten ihrer Familie.
When planning, she takes her family's working hours into account.
Im Garten nehmen wir wegen des Lärms Rücksicht auf die Nachbarn.
In the garden, we take the neighbors into consideration because of the noise.
