(4x)^2=l^2+l^2

解

(4 x)^{2} = l^{2} + l^{2}

解

x = \frac{l}{2 2}, x = - \frac{l}{2 2}

解答ステップ

(4 x)^{2} = l^{2} + l^{2}

類似した元を足す:

l^{2} + l^{2} = 2 l^{2}

(4 x)^{2} = 2 l^{2}

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

の場合, 解は

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

解く

4 x = 2 l^{2} : x = \frac{l}{2 2}

解く

4 x = - 2 l^{2} : x = - \frac{l}{2 2}

二次equationの解:

x = \frac{l}{2 2}, x = - \frac{l}{2 2}

x^{2} + 42 = 13 x

11 x^{2} - 2 = 0

4 x^{2} - 18 x + 14 = 0

r^{2} = - 2

9(x^2-10)+14=-12

9 (x^{2} - 10) + 14 = - 12
