Write the expanded form of the expression. <br> -1/2 (y - x) = ?

morpeh [17]

Answer:

The expanded form of the expression $-\frac{1}{2}(y-x)$ is $\mathbf{-\frac{1}{2}(y)+\frac{1}{2}(x)}$

Step-by-step explanation:

We need to write expanded form of the expression $-\frac{1}{2}(y-x)$

For expansion we will use distributive property of multiplication over addition

$a(b+c)=ab+ac$

Applying above rule:

$-\frac{1}{2}(y-x)\\=-\frac{1}{2}(y)-(-\frac{1}{2}(x))\\=-\frac{1}{2}(y)+\frac{1}{2}(x)$

So, the expanded form of the expression $-\frac{1}{2}(y-x)$ is $\mathbf{-\frac{1}{2}(y)+\frac{1}{2}(x)}$
