(X/(29.4))^2+((40)/(46.2))^2=1

解答

(\frac{X}{29.4})^{2} + (\frac{40}{46.2})^{2} = 1

解答

X = 14.71142 \dots, X = - 14.71142 \dots

求解步骤

(\frac{X}{29.4})^{2} + (\frac{40}{46.2})^{2} = 1

将

(\frac{40}{46.2})^{2}

到右边

(\frac{X}{29.4})^{2} = 1 - \frac{1600}{2134.44}

化简

1 - \frac{1600}{2134.44} : \frac{534.44}{2134.44}

对于

(g (x))^{2} = f (a)

解为

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

解

\frac{X}{29.4} = \frac{534.44}{2134.44} : X = 14.71142 \dots

解

\frac{X}{29.4} = - \frac{534.44}{2134.44} : X = - 14.71142 \dots

二次方程组的解是:

X = 14.71142 \dots, X = - 14.71142 \dots

450000=-425x^2+45500x-650000

450000 = - 425 x^{2} + 45500 x - 650000

8^{2} + x^{2} = 7^{2}

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

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

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

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