expand (s-2pi)(s+2*pi)

expand

(s - 2 \cdot π) \cdot (s + 2 \cdot π)

s^{2} - 4 π^{2}

Solution steps

(s - 2 π) (s + 2 π)

Apply Difference of Two Squares Formula:

(a - b) (a + b) = a^{2} - b^{2}

a = s, b = 2 π

= s^{2} - (2 π)^{2}

Simplify

s^{2} - (2 π)^{2} : s^{2} - 4 π^{2}

= s^{2} - 4 π^{2}

2 (\frac{1 - 5 y}{2}) y + 5

\frac{w}{( s ^{2} + w ^{2} ) ( s + a )}

\frac{1}{s ( s - 1 )} + (2 s + 1)

\frac{k ( k + 1 ) ^{3} ( 2 k + 1 )}{6}

\frac{2 x ^{2} - 4 x - 16}{3 ( x + 3 )}
