Linear :

Always in the form ax + b = c

Therefore the general solution of x is \(\frac{c-b}{a}\)

Quadratic:

ax^2 + bx + c = 0

Let there are 2 numbers p and q where b is always p+q and c is always pq.

(There is always 2 numbers which satisfies these conditions frown)

(ax+p)(x+q) = 0

general solution of x : x = -p/a or x = -q

the Cubic Formula is kept as a secret by the mathematicians in 1600s so we never know how to obtain solutions of cubic equations other than factorization or until some people get the Cubic formula eventually (?) and shares to all people.....

That will be one more chapter in maths book...... frown. LOL.
