Expand (a+b)2
Expand and distribute algebraic expressions using FOIL and distribution.
Expression
Answer
2a + 2b
To expand an expression means to multiply out all products and remove parentheses. Let's check if there's anything to expand.
2a + 2b
This expression is already fully expanded.
2a + 2b
How to expand (a+b)2
To expand (a+b)2, distribute each term across the other factor and combine like terms. The result is 2a + 2b.
This is a algebraic expansion — we multiply out brackets and simplify. For binomials, the FOIL method (First, Outer, Inner, Last) is commonly used.
Frequently asked questions
What is the answer to (a+b)2?
The answer is 2a + 2b.
What method is used?
the distributive property (FOIL for two binomials) — multiply each term in one factor by every term in the other, then combine like terms.
