Factoring Out a Negative GCF
Factoring Out a Negative GCF is a Grade 7 math skill from enVision, Mathematics, Grade 7, covering Generate Equivalent Expressions. When the leading term of an expression is negative, it is a common convention to factor out a negative GCF. This changes the sign of all the terms inside the parentheses. Explanation When an expression's first term is negative, it is standard practice to make the GCF negative. Dividing each term by a negative number changes the sign of every term remaining inside the parentheses.
Key Concepts
When the leading term of an expression is negative, it is a common convention to factor out a negative GCF. This changes the sign of all the terms inside the parentheses. $$ ax ay = a(x+y)$$ $$ ax + ay = a(x y)$$.
