Question 754360
To the nearest ten minutes, find all values of x in the interval 0 less than or equal to x less than or equal to 360 that satisfy {{{ 3tan^2(x)+5tan(x)=2 }}}
---------
Sub u for tan(x)
{{{3u^2 + 5u - 2 = 0}}}

===========
tan(x) = 1/3
x = 18.435, 198.435 degs
tan(x) = -2
x = 116.565, 296.565 degs
