expand (5sin(x)-1)(5sin(x)+1)

expand

(5 sin (x) - 1) (5 sin (x) + 1)

25 sin^{2} (x) - 1

Solution steps

(5 sin (x) - 1) (5 sin (x) + 1)

Apply Difference of Two Squares

(5 sin (x) - 1) (5 sin (x) + 1) : 25 sin^{2} (x) - 1

= 25 sin^{2} (x) - 1

A + A l e f t (B + C) + Bl e f t (B + C)

\frac{8 ( s + 1 ) ( s + 20 )}{s ( s ^{2} + 5 s + 16 ) ( s + 10 )}

6 (2 - 2)

(3 + 5) (3 + 2)

\frac{9}{( 1 - x ) ( 1 + 2 x ) ^{2}}
