Question

How do you spolve equations using the quadratic formula

Answer 1

solve?

Answer 2

Given a quadratic equation like \[x ^{2}+5x+6\] notice that

a=1 and b = 5 and c = 6

Now substitute into the quadratic formula

\[(-b \pm \sqrt{b ^{2}-4ac})/(2a) = (-5\pm \sqrt{25-24})/2\]

which simplifies to

-2 and -3
