Question

can someone please help me

Solve x2 + 6x + 7 = 0.

Answer 1

Are we supposed to use the quadratic formula?

Answer 2

yes @pooja195

Answer 3

Alright
\[\huge~\rm~x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]
This is the formula we need to find our abc values
Do you know how?

Answer 4

yes b is the 6 c is the 7 but idk a @pooja195

Answer 5

Ok
We use the standered equation to determine the abc values which is this:
\[\huge~\rm~ax^2+bx+c=0\]

Answer 6

Match it up with your equation
\[\huge~\rm~ x^2 + 6x + 7 = 0.\]

Answer 7

Can you tell me what the a and c values are now?

Answer 8

1 and 7? @pooja195

Answer 9

Yes so our
a=1
b=6
c=7
\[\huge~\rm~x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]
Now we need to plug the numbers in
\[\huge~\rm~x=\frac{ -(6) \pm \sqrt{(6)^2-4(1)(7)} }{ 2(1)}\]

Answer 10

Can you simplfy that?

Answer 11

yes @pooja195

Answer 12

would the -6 on the outside of the sqrt sign stay negative or posotive

Answer 13

it remains negative

Answer 14

i didnt get what any of my answer choices were @pooja195

Answer 15

Thats because there is still another part

Answer 16

@pooja195
ok then i think i simplified it correctly

-6+_ sqrt of -16 / 2

Answer 17

\[\huge~\rm~x=\frac{ -6 \pm \sqrt{8} }{ 2}\]

Answer 18

What are your answer chocies?

Answer 19

how do i take a screen shot of the window
@pooja195

Answer 20

Im not sure...

Answer 21

Is that an option?

Answer 22

yes that is

Answer 23

Thats the simplified form of the equation i wrote above thats your final answer :)

Answer 24

thank you so much

Answer 25

No problem :)
