Answers to Questions

How to develop and reduce a polynomial-like expression?

The development allows expressing the polynomial in a addition (sum) or subtraction (difference) of factors. The reduction is used to group each factor of the polynomial or simplify the result.

Example: \( (a+b)^2-2ab \) can be expanded \( a^2+2ab+b^2-2ab \) and then be reduced \( a^2+b^2 \)

The development and reduction operations is a basic maths calculation in middle school.

How to develop and reduce a fraction?

dCode offers dedicated tools for calculating fractions. The development consists of writing fractions to the same denominator and reducing is the simplification to the least common multiple.

How to expand and reduce a trigonometric expression?

dCode can develop trigonometric expressions to simplify (reduce) their content (the goal is to reduce the content (between parenthesis) of the sine and cosine functions)
