x^2= 9/256

解

x^{2} = \frac{9}{256}

解

x = \frac{3}{16}, x = - \frac{3}{16}

+1

十進法表記

x = 0.1875, x = - 0.1875

解答ステップ

x^{2} = \frac{9}{256}

x^{2} = f (a)

の場合, 解は

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

x = \frac{9}{256}, x = - \frac{9}{256}

\frac{9}{256} = \frac{3}{16}

- \frac{9}{256} = - \frac{3}{16}

x = \frac{3}{16}, x = - \frac{3}{16}

quadraticformula 3x+18=x^2

q u a d r a t i c f or m u l a 3 x + 18 = x^{2}

(6 - x)^{2} = 64

solvefor x,f(x+3)=3x^2+3x-3

so l v e f or x, f (x + 3) = 3 x^{2} + 3 x - 3

(2-x)(x+1)-x(x-1)=2

(2 - x) (x + 1) - x (x - 1) = 2
