Question in the screenshot please help1

Answer 1

B

Answer 2

Explain pls

Answer 3

You must explain you're answer. (:

Answer 4

x^2 + 6x = 5


divide coefficient of x by 2

(x +3)^2 - 9 = 5

simplify a little more and you have it

Answer 5

( x+3)^2 = 14

Answer 6

how

Answer 7

Do you know about completing square?

Answer 8

you use the identity
x^2 + ax = (x + (a/2)^2 - a^2/2^2

Answer 9

in this case we illustrate it as follows

x^2 + 6x = (x +3)^2 - 9 = x^2 + 6x + 9 - 9 = x^2 + 6x

Answer 10

B is the correct answer
\[x^{2}+6x=5\]
\[(x+\frac{ 6 }{ 2 })^{2} - (\frac{ 6 }{ 2 })^{2}=5\]
\[(x+3)^{2} = 14\]
and these are the steps

Answer 11

And that is completing square :)

Answer 12

divide the coefficient of x by 2 then subtract the square of this result

Answer 13

Thanks!

Answer 14

Can you guys help with another

Answer 15

the same steps and then take the root for the two sides and let x be on a side alone
