factor 1-tan^2(a)

factor

1 - tan^{2} (a)

(1 + tan (a)) (1 - tan (a))

Solution steps

1 - tan^{2} (a)

Rewrite

1

1^{2}

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

Apply Difference of Two Squares Formula:

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

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

= (1 + tan (a)) (1 - tan (a))

\frac{( 2 x ^{3} + 4 x ^{2} + 2 x )}{( 6 x ^{3} - 6 x )}

cos^{3} (x) + cos (x)

\frac{n !}{n ! ( n + 1 )}

\frac{- 56 x y ^{5} z ^{2}}{- 8 x y ^{2} z ^{2}}

8 a^{2} b (a - b)^{2} - 4 a^{2} (a - b)^{3}
