Question

Quadratic Equation help

Answer 1

I am usually ok with these but thise one got me confused >.<

\[\frac{ -4 \pm \sqrt( 4^2 - 4(1*3)}{ 2(1) }\]

Answer 2

what's confusing?

Answer 3

I know simplified it would look like

\[\frac{ -4 \pm \sqrt12 }{ 2 }\]

whic would simplify down to

\[\frac{ -4 + 4 }{ 2 } or \frac{ -4 - 4 }{ 2 }\]

prolem is that the only possible answers the question givs are

A 1, 3
B -1, 3
C 1, - 3
D -1, -3

Answer 4

And I am getting 0/2 (impossible fraction) and -8/2 which simplifiys down to -4,

and n/a, -4 isnt an option :/

Answer 5

hmmm, \(\sqrt{12} \ne \pm 4\)

Answer 6

I meant sqrt of 4 which equals 2

Answer 7

still it wouldnt make sense

Answer 8

hmm, I see

Answer 9

what's the original equation?

Answer 10

ohh one sec

Answer 11

its at the top

Answer 12

$$
\frac{ -4 \pm \sqrt{ 4^2 - 4(1\times3)}}{ 2(1) } \implies
\cfrac{-4\pm\sqrt{16-12}}{2}\\
\implies \cfrac{-4\pm\sqrt{2^2}}{2} \implies
\cfrac{-4\pm2}{2}
$$
