Hi, Hope I can help,
.
factor -9b+63
.
First we need to find what is in common in both terms ( -9b and "63")
.
They both have a (-9) in common, now divide both terms by (-9)
.
=
.
=
.
Now we can combine the two answers, which equals , this makes up the second factor, first is (-9)
.
The factored form =
.
You would get the original polynomial if you used the distribution method
.
= = , remember the signs
.
, our original polynomial, they most likely want you to have "b" positive, so is your answer
.
Here is another way of factoring
.
They both have a "9" in common, now divide both terms by "9"
.
= =
.
=
.
Now we can combine the two answers, which equals , this makes up the second factor, first is "9"
.
The factored form = , we can check by distribution
.
= = (Remember signs)
.
, our original polynomial
.
They most likely want your "b" to be positive, so your factored answer is
.
