expand (10sin(x)-1)(10sin(x)+1)

expand

(10 sin (x) - 1) (10 sin (x) + 1)

100 sin^{2} (x) - 1

Solution steps

(10 sin (x) - 1) (10 sin (x) + 1)

Apply Difference of Two Squares

(10 sin (x) - 1) (10 sin (x) + 1) : 100 sin^{2} (x) - 1

= 100 sin^{2} (x) - 1

\frac{( 5 - x ) ^{2}}{2}

n (\frac{ln ( n + 1 )}{ln ( n )} - 1)

\frac{( 2 x + 5 ) ^{2}}{4}
