Answer:
2x is a common factor because it can be used to dive all three values without a remainder
Step-by-step explanation:
A factor is a number that can divide another number perfectly. That is without anything remaining.
We will now divide each of the expressions by 2x to show that 2 x is a factor of all three expressions
<em>4x2</em> divided by <em>2x</em>
In this, <em>2x</em> will cancel out <em>x2</em> to give 4 as the answer.
This shows 2x is a factor.
<em>8xy</em> divided by <em>2x</em>
In this, x will divide x to give 1
2 will divide 8y to give 4y.
This shows 2x is a factor, since there was a perfect division throughout.
6wx divided by <em>2x</em>
In this, x will divide x to give 1
2 will divide 6w to give 4y.
This shows 2x is a factor, since there was a perfect division throughout.
Therefore, 2x is a common factor of the three expressions below 4x2, 8xy and 6wx
