-4 (+-) sqrt -44 -------------- 6 Whats next?

OpenStudy (anonymous):

How did you get?$\sqrt{-44}$You can't square root a negative, check your math again.

OpenStudy (anonymous):

3x2 + 4x = -5

OpenStudy (anonymous):

came from this using the quadratic equation

OpenStudy (anonymous):

$x=\frac{-4 \pm \sqrt{-44}}{6}$$x=\frac{-4 \pm 2\sqrt{-11}}{6}$$x=\frac{-2 \pm i\sqrt{11}}{3}$

OpenStudy (anonymous):

x =$(-4\pm \sqrt{-44})/6$

OpenStudy (anonymous):

$\sqrt{-1}=i$ This answer is in the complex plane

OpenStudy (anonymous):

$3x^2+4x-5=0$Quadratic Equation$((-4)+-\sqrt{(4)^2-4(3)(5)})/2(3)$$(-4+-\sqrt{-44})/6$Zed's right, complex plane. I hate imaginary numbers.

OpenStudy (anonymous):

Zed, how do you get your equations all over 6 like that?

OpenStudy (anonymous):

$(-4\pm \sqrt{44(i ^{2})})/6$ $(-4\pm i \sqrt{44})/6$ $(-4\pm i \sqrt{2*2*11})/6$ $(-4\pm 2i \sqrt{11})/6$ Take 2 as common from the numerator $2(-2\pm i \sqrt{11})/6$ $(-2\pm i \sqrt{11}) / 3$
