Final answer:
To expand the expression -1/4(yx), distribute the multiplier -1/4 to the term yx, resulting in the expanded form -yx/4.
Step-by-step explanation:
The expression given is -1/4(yx). The goal is to write this expression in an expanded form. To do this, we need to distribute the multiplication across the terms inside the parentheses.
Since there are no parentheses actually enclosing individual terms within (yx), the expanded form simply involves multiplying each term inside the parentheses by -1/4. This gives us:
-1/4 × y × x, which can also be expressed as -y/4 × x or -yx/4.
Note that if we had specific numerical values for y and x, we could calculate this further, but without those values, this is the fully expanded form using algebraic notation.
