Multiply the first two factors by the FOIL method. Then multiply the result by the third factor, either horizontally or vertically.madeleine_123 said:Homework Statement
Expand and simplify algebraic expressions.
Homework Equations
(2a+1)(3a-1)(a-2)
The Attempt at a Solution
The problem is, we normally always do these problems with only two sets of brackets. I tried just multiplying each number will each other number but it didn't work.
You say you know how to simplify what's in blue? So go ahead and do that.madeleine_123 said:(2a+1) · (3a-1)(a-2)
Expanding an algebraic expression involves multiplying out the terms and simplifying the resulting expression. This is often done to make the expression easier to work with or to solve for a variable.
To expand a binomial expression, use the FOIL method: multiply the First terms, then the Outer terms, then the Inner terms, and finally the Last terms. Simplify the resulting expression by combining like terms.
Sure, let's simplify the expression 3x + 6x - 2x. First, combine like terms to get 7x - 2x, which simplifies to 5x. So the simplified expression is 5x.
Simplifying algebraic expressions helps make them easier to understand and work with. It also allows us to see patterns and make connections between different expressions, making it easier to solve equations and manipulate them in various ways.
To check if two expressions are equivalent, substitute in a few values for the variables and see if the resulting values are the same for both expressions. You can also use algebraic techniques, such as factoring, to see if the two expressions can be written in the same form.
