Factoring is a process used in algebra where we write an expression as a product of its factors. The expression we will be factoring is -6m + 9.
Here is how to factor this expression:
1. The first step in factoring an expression is to identify any common factors between the terms. Looking at both -6m and 9, you can notice that they have a common factor of 3.
2. Once we identify a common factor, we "factor it out", by dividing each term in the expression by this common factor.
Divide -6m by 3, yeilding -2m.
Divide 9 by 3, yieldings 3.
3. Replace the original expression with the common factor multiplied by the result from the step above.
Therefore, -6m + 9 factors to 3(-2m + 3).
