factor cos^2(x)-sin^2(x)

factor

cos^{2} (x) - sin^{2} (x)

(cos (x) + sin (x)) (cos (x) - sin (x))

Solution steps

cos^{2} (x) - sin^{2} (x)

Apply Difference of Two Squares Formula:

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

cos^{2} (x) - sin^{2} (x) = (cos (x) + sin (x)) (cos (x) - sin (x))

= (cos (x) + sin (x)) (cos (x) - sin (x))

144 y^{4} - 121 x^{2}

5 x^{3} - 65 x - 60

(2 x + 2 h - 5)^{2}

(x + 4) (x + 2)
