Question

quadratic formula to solve x2 + 8x = –2

Answer 1

X^2+8X+2=0
X=-8+ ROOT(56)
------------
2
OR
X=-8 - ROOT(56)
------------
2

Answer 2

ax^2+bx+c=0
\[ x=(-b+\sqrt(b^2-4ac))/2a\]
\[ x=(-b-\sqrt(b^2-4ac))/2a\]

Answer 3

here a=1 b=8 c=2
b^2-4ac=56
so
\[ x=(-8+\sqrt(56))/2\]
or
\[ x=(-4+\sqrt(14))\]
and
\[ x=(-4-\sqrt(14))\]
