SYNTHETIC and FACTORING...?

Question

This is the problem:

After doing everything, my result was:

x^2 - x - 6
And factored:
(x - 3)(x + 2)
x = 3, x = - 2

It says my answer is wrong, however. What was my mistake?

Answer 1

Hi,
What you've done is correct, but it looks as if you have given your answer in the wrong form. The problem says this: ""then use the results to factor the polynomial into these factors"
(x+A)(x+B)(x+C
That's this:
(x+1)(x-3)(x+2)
Then it says:
Give the list of values A,B,C you obtain. That's this:
1,-3, 2

Read the problem carefully and I think you'll see what's needed.

Hope this helps.
