Question

Solve x^2 + 6x + 7 = 0. quadratics using the quadratic formula

Answer 1

root2 -3

Answer 2

& -3 -root2

Answer 3

possible answers are x=-1andx=-5 , 3+_sqrt2, -3+-sqrt2, -3+-sqrt2/2

Answer 4

-1 and -5 not possible

Answer 5

Using the quadratic equation:
ax^2 + bx + c = 0
we have: a =1 b = 6 c = 7
Then we plug into the quadratic formula:
\[-b \pm \sqrt{b^{2}-4ac}/2a\]
We get the following solutions:
x = -1, -5, 3 + sqrt(2), 3 -sqrt(2),
