x^2=24^2+26^2

解答

x^{2} = 2 4^{2} + 2 6^{2}

解答

x = 2313, x = - 2313

+1

十进制

x = 35.38361 \dots, x = - 35.38361 \dots

求解步骤

x^{2} = 2 4^{2} + 2 6^{2}

化简

2 4^{2} + 2 6^{2} : 1252

对于

x^{2} = f (a)

解为

x = f (a), - f (a)

x = 1252, x = - 1252

1252 = 2313

- 1252 = - 2313

x = 2313, x = - 2313

(D^{2} + 1) = 0

0 = 3 x^{2} - 9 x - 54

-9x^2+18x+135=0

- 9 x^{2} + 18 x + 135 = 0

x^{2} + 32 x = 0

1+4+7+(3n-2)= 1/2 (3n^2-n)

1 + 4 + 7 + (3 n - 2) = \frac{1}{2} (3 n^{2} - n)
