Question

Solve by using the quadratic formula to solve x2 + 6x = -3. (1 points)

Answer 1

First, add 3 to both sides of the equation.
Then use the quadratic formula with a = 1, b = 6, and c = 3.
Post what you get and ask questions if you have any.

Answer 2

I go t -6 +- squareroot 24 over 2

Answer 3

I did something wrong

Answer 4

Good so far. Now simplify.

Answer 5

when I simplified I got -6 +- sroot 12

Answer 6

You have this so far, right?

\( x = \dfrac{-6 \pm \sqrt{24}}{2} \)

Answer 7

yes

Answer 8

\( \sqrt{24} = \sqrt{4 \times 6} \)
You can pull out \(\sqrt{4} = 2\), giving you \(2\sqrt{6} \).

Answer 9

that isn't an option I got that also as I continued

Answer 10

We're simplifying, We're not done yet. We'll get to the answer soon.

\(x = \dfrac{-6 \pm \sqrt{24}}{2}\)

\(x = \dfrac{-6 \pm 2\sqrt{6}}{2}\)

\(x = \dfrac{(2)(-3) \pm (2)\sqrt{6}}{2}\)

\(x = \dfrac{(2)[-3 \pm \sqrt{6}]}{2}\)

\(x = -3 \pm \sqrt{6}\)
