factor tan^2(x)-1

factor

tan^{2} (x) - 1

(tan (x) + 1) (tan (x) - 1)

Solution steps

tan^{2} (x) - 1

Rewrite

1

1^{2}

= tan^{2} (x) - 1^{2}

Apply Difference of Two Squares Formula:

x^{2} - y^{2} = (x + y) (x - y)

tan^{2} (x) - 1^{2} = (tan (x) + 1) (tan (x) - 1)

= (tan (x) + 1) (tan (x) - 1)

\frac{1 + cos ( 2 x )}{2}

sin (x) csc (x)

(5 a + 7 b - 3) + (3 b - 2 a + 9)

(\frac{2}{5})^{2} + \frac{11}{25}

\frac{2 2 + 3}{3 2 - 2 3}
