x^2= 15/16

解

x^{2} = \frac{15}{16}

解

x = \frac{15}{4}, x = - \frac{15}{4}

+1

十進法表記

x = 0.96824 \dots, x = - 0.96824 \dots

解答ステップ

x^{2} = \frac{15}{16}

x^{2} = f (a)

の場合, 解は

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

x = \frac{15}{16}, x = - \frac{15}{16}

\frac{15}{16} = \frac{15}{4}

- \frac{15}{16} = - \frac{15}{4}

x = \frac{15}{4}, x = - \frac{15}{4}

x^{2} = \frac{16}{121}

1/4 x^2+sqrt(2)x+2=0

\frac{1}{4} x^{2} + 2 x + 2 = 0

solvefor x,x^2y+x^2-xy^2+xy+2=0

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

(x + 1) (2 x - 5) = 0

- 6 x^{2} - 7 x + 3 = 0
