@zero2pi: Life Changing Quadratic Formula 🤯 #math #mathskills #maths #mathtrick #mathhack

karkadew :

Viette’s better

atomboy :

no onder they don't teach it

Reality :

what an unnecessarily complex and roundabout way to solve a quadratic equation. all of this CNA be derived faster by just completing the square

mothballz42069 :

there's no need to answer it the answer was alr answered it's 0💀

سعد :

leoiscool :

Just use the quadratic formula 😭💔

Alfa :

so basically solving it with viette formulas, which is just another quadratic equation, pointless

Daissam :

x² -5x +6 = 0 x² -2x -3x +6 = 0 x(x-2) -3(x-2) = 0 (x-2)(x-3)=0 x-2=0 or x-3=0 x=2 or x=3

Link :

I wonder where the quadratic formula came from? 🤔

Xx_Pietro_DoesCrack_xX :

seems a bit longer

MakLyk :

I use delta= b**2 -4ac

totallynot.adam :

But you have to remember that the sum of the roots are -b/a

Bread_Pitt :

waaaaay more complicated

⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻JOSHUA⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻⸻ :

M=-b/2a u=sqrt(M²-c/a) x=M-u, M+u

Jim crime :

I just realised, if you put all the steps together and simplify it your essentially at the quadratic formula 😂😂

Saronite :

I remember investing so much time into these math tricks only to end up in a job where only multiplication and division are relevant

Mohamed :

mode 5,3😂

the :

linear algebra in college teaches this

Coleisforrobot :

completing the square is so much simpler, all you need is basic algebra

Alexander Hoggarth 𝄞 :

how is this different to viettes method

lil ush :

I teach my students this méthode too

albingranqvist :

Pq-formula

Leon :

the fact that 99% of ppl couldn't solve the example at the end

Sc. Ry :

Dawg just subtract 1 x from the power and have x - 5 plus 6 equals 6

Paakwesi Amofah :

X=0.77 or 4.73
