Answer 1

Medals will be awarded when I return. Thanks for replying.

Answer 2

\[(-b \pm \sqrt{b^2-4ac})/2a\]
a=1,b=4 and c=2
just plug in the values

Answer 3

\[x=\frac{-b \pm \sqrt{b^2-4ac}}{2a}=\frac{-4 \pm \sqrt{(-4)^2-4(1)(2)}}{2(1)}\]

Answer 4

it should be noted that you must first imagine the eqaution as
ax+bx+c=0 to make sense of the quadratic formula.

Answer 5

\[ax^2+bx+c=0\]

Answer 6

Thank you to all.
