Decompose the following expression into factors:
2xy+4yx
To factor the expression 2xy+4yx, we proceed as follows:
- Step 1: Identify the common factor between the terms.
- Step 2: Factor out the common factor.
- Step 3: Simplify the expression inside the parentheses.
Let's break this down:
Step 1: The expression is 2xy+4yx. Clearly, both terms share 2x as a common factor.
Step 2: Factor out 2x from each term:
- From the first term: 2xy=2x×y.
- From the second term: 4yx=2x×2y1.
Step 3: This gives us:
2xy+4yx=2x(y+2y1)
Thus, the expression can be decomposed into factors as 2x(y+2y1).
2x(y+2y1)
