Question

9x2 + 6x + 1 = 0
x =

Answer 1

this is a perfect square

Answer 2

Can I try? @campbell_st I think I know this
\[x=\frac{ -b \pm \sqrt{b^2-4ac} }{ 2a }\]
Right?

Answer 3

well that will get the answer for you...

Answer 4

\[x=\frac{ -6 \pm \sqrt{6^2-4(9)(1)} }{ 2(9) }\]
\[x=\frac{ -6 \pm \sqrt{36-36} }{ 18 }\]
\[x=\frac{ -6 }{ 18 }\]
x=-3
Right? lol

Answer 5

nope.... -6/18 = -1/3
