2. Solve Quadratic equation by just remembering a formula
First write a,b and c .Input these values into below formula to find roots
This equation has two roots. Let’s call them p and q
The main trick is how to remember this formula. So, here’s the trick
Be a Square b2
Take away -
For AC 4ac
P,Q=(-b±√(b^2-4ac))/2a
First Factor P=(-b+√(b^2-4ac))/2a
Second Factor Q=(-b-√(b^2-4ac))/2a
√(b^2-4ac)
ax2+bx+c=0
First the toughest task, try to remember
Start by memorizing below sentence
Remember this crap being inside a Roof √
Now when this toughest task done.try to imagine whole formula
I hope you guys remember the classic rock Band ACDC
1. 1st
Sentence - “You will be a square if you take away those for AC/DC"
3. Let’s try this formula on an equation:
a=1,b=5,c=6
P=(-5+√(25-24))/2=(-5+√1)/2=(-5+1)/2=(-4)/2=-2
Q=(-5-√(25-24))/2=(-5-√1)/2=(-5-1)/2=(-6)/2=-3
→ p=-2, q=-3
→ x2+5x+6=0
→(x+2)(x+3)=0
x2+5x+6=0
Not be –b
Giving or taking ±
Crap first memory line (Refer to first point)
Sitting on (Divided by)
Double a 2a
2. I will not be giving or taking this crap which is sitting on a double-A battery
