Homework Help: Math

Posted by -Untamed- on Thursday, November 24, 2011 at 9:09pm.

Learning about quadratic functions and equations, and I am struggling. It's so easy for others to understand, but math is my weakness, would appreciate all the help you could give. Notes and stuff would be great, as long as I understand.

Quadratic Functions and Equations, Connecting Zeros, Roots, and x-intercepts

Find the roots of the following equations.

a) 2x(x+3) = 0

I got showed this way from a friend, but teacher never taught this way.

My friend divided 2x by 2 and divided 0 by 2, then he got left with x(x+3)=0 and then he got x = 0, x +3 = 0 and got 0, and -3 as answer. But teacher showed us the graphing way and the table of value thing.

Is there an easier way to do this like factoring or something? Want to learn please, and also do we just plug in any number for the table of value thing?

Find Zero of following equation

x^3 + 8x^2 = 20x
