Question 707140: Am trying to help my God daughter: She's having issues with a problem that I do not understand or remember. Hope you can help with steps such as what is the q mean, know some algebra but the factoring is what's stumping me.
Thank you.
15q^3 power + 40q^2 power + 3q + 8 .
Answer by Stitch(470) (Show Source): You can put this solution on YOUR website!
Given:
In that equation the q is just a variable. It can be replaced by any other letter and still mean the same thing.
--------------------------------------------
You did not mention what you were solving for so I will just factored the equation.
For an equation that goes to the third power, it is usually easier (in my opinion) to group the equation and find the greatest common factor.
For example, group the first two terms and then group the second two terms.

The greatest common factor of the first two terms is 5q^2
The second two terms do not have a common factor and will stay as is.
Rewrite the equation.

Notice that both parts now contain a (3q + 8). You can factor that out and rewrite the equation.

I hope that helps.
