Solve the equation below for all values of theta On the interval 0(degrees) is less than or equal to theta which is less than or equal to 360(degrees)
2tan^2theta -3tan theta -5=0

(2tanx-5)(tanx+1)=0
..
2tanx-5=0
tanx=5/2
x=68.2˚, 248.2˚ (in quadrants I and IV where tan>0)
or
tanx+1=0
tanx=-1
x=135˚, 225˚ (in quadrants II and III where tan<0)
