Simply (tan^2 x - sec^2 x)(sin^2 x + cos^2 x)
kati45 [8]

we can use pythagorean identieis

remember that sin^2(x)+cos^2(x)=1

also remember that tan(x)=\frac{sin(x)}{cos{x}} and sec(x)=\frac{1}{cos(x)}

so if we take sin^2(x)+cos^2(x)=1 and divide both sides by cos^2(x) we get

\frac{sin^2(x)}{cos^2(x)}+\frac{cos^2(x)}{cos^2(x)}=\frac{1}{cos^2(x)}

(\frac{sin(x)}{cos(x)})^2+1=(\frac{1}{cos(x)})^2

tan^2(x)+1=sec^2(x)

subtracting 1+sec^2(x) from both sides

tan^2(x)-sec^2(x)=-1

now subsitute into original problem


\frac{tan^2(x)-sec^2(x)}{sin^2(x)+cos^2(x)}=

\frac{-1}{1}=

-1

the answer is -1
