Distribute
Expand

To multiply out the parts of an expression. Distributing is the opposite of factoring.

 Example 1: 3x(x + 8) = 3x·x + 3x·8                 = 3x2 + 24x Example 2: (x + 2)(x + 5) = x(x + 5) + 2(x + 5)                        = x·x + x·5 + 2·x + 2·5                        = x2 + 7x + 10 Example 3: (x – 3)4 = (x – 3)(x – 3)(x – 3)(x – 3)              = (x·x – x·3 – 3·x + 3·3)(x·x – x·3 – 3·x + 3·3)              = (x2 – 6x + 9)(x2 – 6x + 9)              = x2(x2 – 6x + 9) – 6x(x2 – 6x + 9) + 9(x2 – 6x + 9)              = x2·x2 – x2·6x + x2·9 – 6x·x2 + 6x·6x – 6x·9 + 9·x2 – 9·6x + 9·9              = x4 – 6x3 + 9x2 – 6x3 + 36x2 – 54x + 9x2 – 54x + 81              = x4 – 12x3 + 54x2 – 108x + 81
