Answer 1

Where is the list of methods?

Answer 2

Methods:
Completing the Square
Factoring
Quadratic Formula
Graphing

those :)

Answer 3

Are you able to use any of the methods to solve?

Answer 4

yep , im just really confused on how to

Answer 5

Let's start with graphing. The graphing method involves exacty what its name implies. You must graph the equation. The problem is that reading the solution off the graph is not easy if the solution is not exactly on the intersection of the grid.

Then there is factoring. Factoring is a good method, but it only works when the polynomial is factorable. Not every polynomial can be factored.

Completing the square and the quadratic formula always work. In fact the way to derive the quadratic formula is by completing the square. The use of one or the other is just personal preference.

Answer 6

ok so completing the square?

Answer 7

I'd say, graphing should be ruled out because it's not practical.
You can try factoring.
If factoring does not work because the polynomial is not factorable, then move on to the quadratic formula.

Answer 8

You can do completing the square if you prefer, but I think it's more work that the quadratic formula.

Answer 9

could you help me solve it .. its so confusing and stressful , i dont know the fiirst step

Answer 10

Let's use the quadratic formula.
