with lines

I mean with like quadratic equations...

u add square of half the coefficient of x to both sides.....

if u give a question I can explain..

Got it!

good for u then....☺

it will give you C = 25.
Thats the number you were looking for ;)

I've found this out by myself when i was in college. It was very useful for my advanced math classes

25 = 5² which is square of half of the coefficient of x as I said !!!

well.. here is the proof of what you said then.
only words doesnt mean anything :p

could I have another example?

Just to get it in my brain :)

abstract: ax^2 +bx +c
c = (b/2)^2

x^2 + 4x + C
4x = 2x*sqrt(C)
2 = sqrt(C)
C = 4
so: x^2 + 4x + 4 = perfect square

thats if a=1 i believe

thnx!

Thanks guys!

no prob
