You might be thinking of "distribution" or "distributive property"
Example:
2(3x+5) = 2*3x+2*5 = 6x+10
I multiplied the outer 2 by each term inside (3x and 5)
Answer:
Distributive property
Step-by-step explanation:
Remark
Usually it is the Distributive property. There has to be a plus or minus sign that connects two or more terms that can't be reduced any further.
Example One
5(x + y + 2) Three terms which cannot be added together.
5x + 5y + 10 Distributive Property.
Example Two
- x (2y + 3x^2 - 4)
-2xy - 3x^3 + 4x Distributive Property
