If those lines are absolute value then the answer is 0 if they are supposed to be parenthesis then the answer is -6
<span> tan(x)/ cos(x)-sec(x)
tanx/(cosx-1/cosx)
tanx/cos^2x-1)--------------------1-sin^2x=cos^2x
-tanx/sin^2x
-(sinx/cosx)/sin^2x
-1/sinxcosx
multiply 2/2
-2/2sinxcosx-------------sin2x=2sincosx
-2/sin2x------------------1/sinx=cosecx
-2cosec2x</span>
Answer:
this should be right if not comment and I'll relook it.
FOIL Method.
You will get the same answer x^2+ 7x- 18
Answer:
Use a calculator solved :)))
