Answer by rapaljer(4671)   (Show Source):
You can put this solution on YOUR website! First, you have to set this equation equal to zero:
10x^2 +100x = 0
Next factor the common factor which is 10x:
10x(x+10)=0
Solve this in TWO parts!
10x=0
x=0
x+10=0
x=-10
For additional help with this type of problem, please see my own website by clicking on my tutor name anywhere in algebra.com. Look for the link on my homepage "Basic, Intermediate, and College Algebra: One Step at a Time." Select "Basic Algebra", Chapter 2, and look for "Solving Quadratic Equations". See also my page called "MATH IN LIVING COLOR", again, Basic Algebra, Chapter 2. There I have a lot of problems like this solved in "Living Color".
