Question

Which of the following equations is used in this process?

Answer 1

Solve \[x^2+9x+7=0\] by completing the sqaure.

Answer 2

there is 2 solutions

Answer 3

x =(9-√53)/-2=-0.860
x =(9+√53)/-2=-8.140

Answer 4

You would first divide 9x by 2 to get 4.5 and then square 4.5 so

x^2 +9x + 20.25 = 13.25

Answer 5

What are the answer choices?

Answer 6

was i right @sweetburger

Answer 7

No clue didnt sit through and bother with the quadratic cus the question is asking for an equation not a solution set for x values

Answer 8

\[4x^2+36x+81=53\]
\[4x^2+28x+49=58\]
\[4x^2+9x+81=72\]

Answer 9

Ok so the answer needs to be in whole numbers so we multiply the entire equation above by 4 like this
4*(x^2 +9x + 20.25 = 13.25) =

4x^2 +36x +81 =53

Answer 10

Oooh way to go, thanks sweet<3
