This would give us:

$(1)^2-4(3)(-2)$

Now, can you compute this expression following the rules of arithmetic?

how do you make more posts.For future topics, I highly recommend using a title that briefly describes the problem. For example, a good title for this topic is "Evaluating a variable expression". This lets our helpers know exactly what kind of problem is being discussed.

We do request that as you learn from the help given in previous problems that you apply this to subsequent problems, and show what you think you should do. This allows us to see how you are progressing, and what things may need to be made more clear.

All of the staff and helpers (official or otherwise) are glad to help others gain a better understanding of mathematics.
