## Mathematical Expression Simplifier

## Answers to Questions

### How to simplify a math expression?

To simplify an equation, or an algaebrical calculation, dCode simplifier expands or factorize items in the expressions in order to reduce the mathematical expression into a simpler form.

Example: $$ \frac{x^2-4}{\frac{(x-2) \left(x^2+4 x+4\right)}{x^2-x-6}} = x-3 $$

dCode cal also realize the factorisation of mathematical expressions

Example: $$ 5x+5 = 5(x+1) $$

To simplify an equation or **simplify an expression**, it is necessary to work on each side of the equals sign.

### How to simplify a formula with remarkable identities?

The remarkable identities allow a factorization of the mathematical expression and thus a simplification of its writing.

Example: $ (x-1)(x+1) = x^2-1 $

### How to simplify radix (roots) expression?

dCode **simplifies algebra expressions** with radicals (nth root), for example by taking out the squares under the root. Square roots can be indicated with the sqrt() function.

Example: $$ \sqrt{8}+\sqrt{2} = 3\sqrt{2} $$

### How to simplify fractions to irreducible form?

dCode calculator create irreducible fractions (see gcd) and reduce them to the same denominator : their lowest common multiple (see lcm).

Example: $$ \frac{15}{8} - \frac{2}{3} = \frac{29}{24} $$
