Question

1/4x^2+12=0

Answer 1

multiply both sides by 4.

x^2 + 48 = 0
x^2 = -48
x = 4i √3

Answer 2

\[1/4x^2+12=0\]\[1/4x^2+12\color{red} {-12}=0\color{red} {-12}\]\[1/4x^2=-12\]\[1/4x^2\color{red} {\times 4}=-12\color{red} {\times 4}\]\[x^2=-48\]\[x=±4i \sqrt{3}\]

Answer 3

thank you soo much!

Answer 4

Anytime!
