64^2=2x^2

解答

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

解答

x = 322, x = - 322

+1

十进制

x = 45.25483 \dots, x = - 45.25483 \dots

求解步骤

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

交换两边

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

6 4^{2} = 4096

2 x^{2} = 4096

两边除以

2

x^{2} = 2048

对于

x^{2} = f (a)

解为

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

x = 2048, x = - 2048

2048 = 322

- 2048 = - 322

x = 322, x = - 322

流行的例子

(a - 2) (a - 4) = 0

solvefor x,f(x+2)=x^2

so l v e f or x, f (x + 2) = x^{2}

a^2x^2-11/6 ax-215/144 = 121/144

a^{2} x^{2} - \frac{11}{6} a x - \frac{215}{144} = \frac{121}{144}

x^{2} + x = 0.1

solvefor x,x^2-2px+p^2-q^2=0

so l v e f or x, x^{2} - 2 p x + p^{2} - q^{2} = 0
