Answers to Questions

How to develop a polynomial-like expression?

dCode can expand and reduce mathematical expression in order to express it in sum of factors.

(a+b)^2 gives a^2+2ab+b^2

The development consists of the transformation of a multiplication or a mathematical product into a sum or a difference. The expansion is also called a development (eg. for a polynom).

To achieve the operations, dCode uses the distributive property of multiplication over addition and subtraction.

After expansion, dCode automatically calculates the reduced form of the expression
