To mulitply by each term inside parentheses is called what?

are you talking about the distributive property?

I NEED HELP

To multiply each term inside parentheses by another term is known as the distributive property. The distributive property states that the product of a number or expression and the sum of two terms is equal to the sum of the products of the number or expression and each term separately.

In algebra, this property is written as: a(b + c) = ab + ac.

To apply the distributive property, you would multiply the term outside the parentheses by each term inside the parentheses. For example, if you have the expression 3(x + 4), you would multiply 3 by x and 3 by 4 separately, resulting in 3x + 12.
