化简 (n-2sqrt(2))(n+2sqrt(2))

解答

化简

(n - 22) (n + 22)

n^{2} - 8

求解步骤

(n - 22) (n + 22)

Apply Difference of Two Squares

(n - 22) (n + 22) : n^{2} - 8

= n^{2} - 8

e x p an d \frac{( - 1 ) ^{n}}{( 3 ^{n} \cdot ( 2 n + 1 ) )}

e x p an d A (3 (e^{x} x^{2} + 2 x e^{x}) + (e^{x^{4}} \cdot 4 x^{3}))

e x p an d \frac{s + 1}{( s + 2 ) ( s - 3 )}

e x p an d (z - 1 - i) (z - 1 + i)

e x p an d (L - \frac{t}{2}) (r) (H + \frac{k}{2})^{2}
