Question

Solve for x. x^2+14x+4=0 I tried the quadratic formula and got super confused!

Answer 1

a=1, b=14, c=4

Answer 2

\[x=\frac{-b \pm \sqrt{b ^{2}-4ac}}{2a}\]

Answer 3

I am trying it again...give me one sec.

Answer 4

computer randomly shut off...sorry.

Answer 5

\[x=\frac{-14\pm \sqrt{196-4(1)(4)}}{2}=\frac{-14\pm \sqrt{180}}{2}=\frac{-14\pm6\sqrt{5}}{2}\]
\[x=-7\pm3\sqrt{5}\]

Answer 6

Ok so far I have this \[-14\pm \sqrt{18}/2\]

Answer 7

How did you get 18?

Answer 8

196-4(1)(4)...I am telling you I don't get this stuff.

Answer 9

What is 4(1)(4)

Answer 10

4(1)(4) is 16 and 196-16=180 NOT 18
