搞乜咁科學 #6 - 對戰 Battle ⚔️

歡迎嚟到 搞乜咁科學 GMG Science 第6集！

今集嘅主題係對戰 Battle！⚔️ 今集Keith會講以前啲數學家係點樣死過嘅呢？🧮 Abellona會講細菌同病毒嘅大作戰🔫

喂！好奇心，係時候醒喇 :)

SPEAKER_01 1:07

I'm not going to be able to do that.

unknown 25:00

If you have a few times, you can see that we can see the same thing.

SPEAKER_02 28:42

So you can form completing the square. But it's a good thing. When the cubes with the things together are set equal to some discrete number, find other two that bias differ. You will get into the habit of making the product always equal to the third of the things cubic exactly. The result then of the cubic which properly subtracted will be equal to a principal thing.

SPEAKER_00 44:00

Mm-hmm.

SPEAKER_02 44:04

Come see that or it's out. So I got you got a Zoo cool. Kayee Dano. Come Catano, eh? Cook. Korea San Soga. Yan Hoka. Tin Monhoka. Tin Jan Hoka. Yam. Mosa. Gaimunse. So yeah, we'll see. Yan Yao. Come you see it die. Yep, mm Sam Gaulin. Sam you eat some tongue coi. Hi, my line of day phone. The review co.

SPEAKER_01 45:44

So base of sea hus.

SPEAKER_02 45:59

Some see tatalia see the mhoi and zido bayma. Oh. Come on, get okay. Come on katano gay zaya within the gallery. Come don't you could say like my tatalia the water building form file. Come cut siwana. Come katano, like some ge go mobile.

SPEAKER_00 46:36

Mm-hmm.

SPEAKER_02 46:36

Catano like you solve it to general equations. So you can form general cubic equation. Depressed cubic equation is formed and cube. Substitute length reduced. That's the depressed cubic equation. So x scam b over sum a x cubed term or coefficient. B x square term coefficient, c term coefficient, d a constant term. So x substitution expands. Depressed cubic equation. So you can see that. So we seen that go sick the soft depressed cube equation. So yeah, I'm not sure. Imaginary number.

SPEAKER_01 56:40

Underscore underscore two.

SPEAKER_02 56:51

I think so.
