expand (x+2sqrt(pi))(x-2sqrt(pi))

expand

(x + 2 π) (x - 2 π)

x^{2} - 4 π

Solution steps

(x + 2 π) (x - 2 π)

Apply Difference of Two Squares Formula:

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

a = x, b = 2 π

= x^{2} - (2 π)^{2}

Simplify

x^{2} - (2 π)^{2} : x^{2} - 4 π

= x^{2} - 4 π

16 e^{4 x} \cdot (1 + e^{4 x})

\frac{1}{( x + 3 ) ( x - 2 )}

\frac{x ( 400 - x )}{400}

\frac{( x ^{2} - 3 x + 5 ) ^{2}}{( x - 2 )}

3 (4 x - 1 = - 15)
