factor 9i - 6x-r I
The expression 9i - 6x - r I cannot be factored further because it is a combination of different terms that cannot be simplified.
To factor the expression 9i - 6x - r I, we can first look for common factors among the three terms. However, there is no common factor among them.
Thus, we can proceed by factoring out a negative sign to simplify the expression:
-1(6x - 9i - r)
Next, we can rearrange the terms inside the parentheses:
-1(-r + 6x - 9i)
Now, the expression is in the form of a trinomial. We can factor it by grouping:
-1(-r + 6x) - 1(9i)
Finally, we can factor out common factors from each binomial:
-1(r - 6x) - 9i
Therefore, the factored form of 9i - 6x - r I is -1(r - 6x) - 9i.
To factor the expression 9i - 6x - r, we need to see if there are any common terms that can be factored out. In this case, the expression does not appear to have any common factors that can be factored out.
So, the expression 9i - 6x - r cannot be factored any further.
