Question

Solve x^2 + 27 = 0 and write factors.
I got (x+9)(x+3)
Is this one right?!?

Answer 1

is \(\bf x^2\ or\ x^3?\)

Answer 2

squared

Answer 3

Aren't you missing your middle term?

Answer 4

Is it solve x^2+12x+27?

Answer 5

\(\bf x^2 + 27 = 0 \implies x^2=-27\implies x=\pm\sqrt{-27}
\\ \quad \\
x=\pm\sqrt{27\cdot -1}\implies x=\pm\sqrt{27}\cdot \sqrt{-1}
\\ \quad \\
x=\pm \sqrt{3^2\cdot 3}\cdot \sqrt{-1}\implies x=\pm 3\sqrt{3}\ i\)

Answer 6

If not then ^^ that would make sense

Answer 7

No.. That's what on the paper.

Answer 8

well.... given +27.... it'd yield a negative -27 on the equation...
maybe if you post a screenshot of the material

Answer 9

I'm scanning the sheet now.

Answer 10

It's upside down... Sorry
