simplify (4-4sin(x))(4+4sin(x))

simplify

(4 - 4 sin (x)) (4 + 4 sin (x))

16 cos^{2} (x)

Solution steps

(4 - 4 sin (x)) (4 + 4 sin (x))

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

= 16 cos^{2} (x)

Factor

(4 - 4 sin (x)) (4 + 4 sin (x)) : 16 (1 - sin (x)) (1 + sin (x))

= 16 cos^{2} (x)

(2 w - p) (2 p + w)

\frac{5}{9} \cdot \frac{9}{8}

(p^{2} + p - 6) (p^{2} - 2 p + 1)

1 - \frac{1}{1 + \frac{1}{2}}

(x + 10 y) (x - 10 y)
