Thank you Bonnie. It takes a long time and much effort to make these videos and it motivates me to do more when I get positive feedback. Please use the video any way you think it will help people teach or learn. Steven G Mar 30 | Steven G.
I am doing "solving quadratic equations by factoring" and "zero product property"... in all the examples of factoring, they do NOT have any with fractions - so i'm not sure what to do first. Can you help me to find the solution set for this : 4/5x^{2} = 2x - 4/5 I've tried this: 4/5x^{2 }- 2x +4/5 =0 but now i'm sure what to do next...do I factor or get rid of the fraction part?

Jason, The technique in the video works only when the binomial factors include integers. Here is how I solved the problem you listed. Multiply by 5/4 to get x^{2}- (5/2)x + 1 = 0 Use the quadratic formula to get x = 1/2, 2 (x - 1/2)(x - 2) = 0 Steven May 26 | Steven G.
