2((x+1)/3)^2= 1/2

解

2 (\frac{x + 1}{3})^{2} = \frac{1}{2}

解

x = \frac{1}{2}, x = - \frac{5}{2}

+1

十進法表記

x = 0.5, x = - 2.5

解答ステップ

2 (\frac{x + 1}{3})^{2} = \frac{1}{2}

以下で両辺を割る

2

(\frac{x + 1}{3})^{2} = \frac{1}{4}

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

の場合, 解は

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

解く

\frac{x + 1}{3} = \frac{1}{4} : x = \frac{1}{2}

解く

\frac{x + 1}{3} = - \frac{1}{4} : x = - \frac{5}{2}

二次equationの解:

x = \frac{1}{2}, x = - \frac{5}{2}

((43)/(42.5))n^2-n^2=3

(\frac{43}{42.5}) n^{2} - n^{2} = 3

b(x)=-9x-6+4x^2

b (x) = - 9 x - 6 + 4 x^{2}

solvefor x,x^2+4xy-y^2+3x-8y+2=0

so l v e f or x, x^{2} + 4 x y - y^{2} + 3 x - 8 y + 2 = 0

4.9t^2+294t-2450=0

4.9 t^{2} + 294 t - 2450 = 0

solvefor x,x^2-25m^2=0

so l v e f or x, x^{2} - 25 m^{2} = 0
