QuestionCalculate $(-5 x)(-3 y)-(2 x)(-3 y)$ .

Studdy Solution

STEP 1

Assumptions1. We are given the expression $(-5 x)(-3 y)-( x)(-3 y)$ . We need to simplify this expression3. The variables x and y can represent any real numbers

STEP 2

First, we simplify the multiplication in the expression. $(-5 x)(- y) =15xy$ $(-2 x)(- y) =6xy$

STEP 3

Substitute these results back into the original expression.
$(-5 x)(-3 y)-(2 x)(-3 y) =15xy -6xy$

STEP 4

Now, we simplify the expression by combining like terms. $15xy -6xy =9xy$ So, the expression $(- x)(-3 y)-(2 x)(-3 y)$ simplifies to $9xy$ .
