Factor question
Factor 4g from: 8g^2j - 12g^2hj

Do you mean?: \$\displaystyle 8g^{2j} - 12g^{2hj}\$

I wrote it the way the book shows the problem.

Factor 4g from: 8g^2 j - 12g^3 hj

I'm really confused I've looked in the book and I can not find an example of this problem anywhere.

i think what you mean is:
\$\displaystyle 8g^2j - 12g^3hj \$

If that is the case then it is pretty easy to factor out a 4g.
You would get:
\$\displaystyle 2gj - 3g^2hj\$
You simply divide by 4g.

Factoring out
Just to be more precise:

\$\displaystyle 8g^2j - 12g^3hj\$

to factor out 4g you would write the following:

\$\displaystyle 4g[2gj - 3g^2hj]\$
