can you insert for variables
a=1
b=6
c=7

Answer 2

so the answer would be

Answer 3

close you're missing a number though

Answer 4

would it be over 2

Answer 5

\[\frac{ -6 \pm \sqrt {6^2-4(1)(7)} }{ 2(1) }\]
\[\frac{ -6 \pm \sqrt {36-28} }{ 2 }\]
\[\frac{ -6 \pm \sqrt {8} }{ 2 }\]

Answer 6

What does 8 factor out to?

Answer 7
