Answer 3

\(\bf 16x^2 + 9 = 0\implies 16x^2 =-9\implies x^2= -\cfrac{9}{16}\implies x=\pm\sqrt{-\cfrac{9}{16}}\)

Answer 4

Subtract 9 from both sides first. ..

Have you learned complex/imaginary numbers yet?

Answer 5

\(\bf x=\pm\sqrt{-\cfrac{9}{16}}\implies x=\pm\sqrt{\cfrac{9}{16}}\cdot \sqrt{-1}\implies x =\sqrt{\cfrac{3^2}{4^2}}\cdot \sqrt{-1}\)

Answer 6

these are my answer options, would it be the last one?
