Question 986720
1. What is the first thing you would do in order to use the quadratic formula to solve this equation?

x^2 + 7x = 9
Subtract 9 from each side.
=======================
2. In the following equation, what are the values of a, b, and c?

0 = 5x^2 + 3x - 19
5, 3 and -19 respectively.
=====================
3. Why/how does using the quadratic formula gives us two different roots (or solutions)?
It doesn't always.  Sometimes it's the same root twice, called multiplicity 2.
====================
4. Do ALL quadratic equations give us two roots (or solutions)? Explain your answer.
Yes, but sometimes it's the same root twice as discussed above.
