Question 1120810: Hi, I'm not really sure of this question:
"In the quadratic formula, to find both solutions you
must add and subtract (square root of b2 − 4ac) divided by 2a . What are you
adding and subracting this to? (Hint: consider the graph of the parabola)"
Thanks!

---------
It's -b%2F2a+%2B+sqrt%28b%5E2-4ac%29%2F2a
and -b%2F2a+-+sqrt%28b%5E2-4ac%29%2F2a
