a quadratic problem is really only a way to solve a certain polynomial. if i gave you the equation:
x(squared) + 4x + 4 then you can solve it using the quadratic formula which is:
(b (plus or minus) ( the square root of ) -b(squared) - 4ac )/ 2
the 'a'b'and c' in the equation are these:
ax(squared) + bx + c
a=1 , b=4, and c=4
so (4(plus or minus the square root of) -4(squared) - 4(1)(4))/2
4 (plus or minus the square root of) 16-16/2
16 - 16 =0
and 4/2 is 2
