Does this help in deciding if one has Winter or Summer Diesel #2?

[Perseverando]

Oh heck, I thought everyone knew this. I’ve been doing it that way for years.

[buckalfa]

We were told there would be no math.

[ClearCase_guy]

Common Core says you can’t do it this way.

[Menehune56]

I’ve already got that formula seared in my brain but thanks!

[Leaning Right]

Meh. I watched the video, twice. And I don’t see how this guy’s method is that much better then the old quadratic formula method.

In fact, I like the old method better because it’s more mechanical. You just plug in the numbers and out come the solutions.

Always laughed at multiple choice tests that had you solve quadratic equations.

has developed an easier way to solve quadratic equations.

I saved time in high school by skipping those math classes. Turns out I was right and my parents were wrong, it was useless information that I would never need. My argument was useless at the time.......

Bump for later...

Wow...looks like he re-discovered Descartes!

...oh René Descartes was a drunken fart ..
...I drink therefore I am!

The general solution to the quadratic equation is not that complicated.

Furthermore, the technique demonstrated applies only to the special case of quadratics where a=1. If you add in the complication of a<>1, although I haven't tried to apply this new method, you are going to have more complicated expressions and you might as well have started with the general solution to begin with.

Dr. Loh’s method, which he also shared in detail on his website, uses the idea of the two roots of every quadratic equation to make a simpler way to derive those roots. He realized he could describe the two roots of a quadratic equation this way: Combined, they average out to a certain value, then there’s a value z that shows any additional unknown value. Instead of searching for two separate, different values, we’re searching for two identical values to begin with. This simplifies the arithmetic part of multiplying the formula out.

I guess I live a sheltered life. I can't remember the last time, in the course of my day to day activities, when I've been asked to solve an quadratic equation.

[ealgeone]

I have kids telling me they learned this last year.

[norwaypinesavage]

The article shows the old way with a single equation. If the new way is so easy, why doesn’t the article describe how to do it? Minus b plus and minus the square root of b squared minus four a c all over 2a can be performed in less than a minute with a calculator to do the square root and described in a single sentence. The new method requires you to watch a video??? Every time?

[Right Wing Assault]

Wait a minute! This is useless. Why, because it is wrong to tell the students to get the RIGHT answer because there are no right answers. Just pick two numbers. Or maybe three if you want. Or tell the teacher there is no correct answer.

This guy is racist. He's the one who is making black people beating of Asians. Arrest him.
