Answer 2

hi do the quadratic formula with it,,can you visuallixed it?

Answer 3

tan^2x +5tanx +3=0 this is like
x^2 +5x +3=0 can you see it?

Answer 4

so i get
\[\frac{ -5\pm \sqrt{13} }{ 2 }\]

Answer 5

I get -.6972 or -4.3028 which are not part of my choices

Answer 6

tan x=-4.302775638 --> x=arc tan -4.302775638= -76.92 degrees--> convert them to radians
tanx=-0.6972243623 ---- x= arc tan -0.6972243623=-34.89 degrees --> convert this to radians

Answer 7
