3n^2+4n+4=0

解

3 n^{2} + 4 n + 4 = 0

解

n = - \frac{2}{3} + i \frac{2 2}{3}, n = - \frac{2}{3} - i \frac{2 2}{3}

解答ステップ

3 n^{2} + 4 n + 4 = 0

解くとthe二次式

n_{1, 2} = \frac{- 4 \pm 4 ^{2} - 4 \cdot 3 \cdot 4}{2 \cdot 3}

簡素化

4^{2} - 4 \cdot 3 \cdot 4 : 42 i

n_{1, 2} = \frac{- 4 \pm 4 2 i}{2 \cdot 3}

解を分離する

n_{1} = \frac{- 4 + 4 2 i}{2 \cdot 3}, n_{2} = \frac{- 4 - 4 2 i}{2 \cdot 3}

n = \frac{- 4 + 4 2 i}{2 \cdot 3} : - \frac{2}{3} + i \frac{2 2}{3}

n = \frac{- 4 - 4 2 i}{2 \cdot 3} : - \frac{2}{3} - i \frac{2 2}{3}

二次equationの解:

n = - \frac{2}{3} + i \frac{2 2}{3}, n = - \frac{2}{3} - i \frac{2 2}{3}

b(c-a)x^2+c(a-b)x+a(b-c)=0

b (c - a) x^{2} + c (a - b) x + a (b - c) = 0

solvefor a,588=a^2*b

so l v e f or a, 588 = a^{2} \cdot b

x^2-1000x-30000=0

x^{2} - 1000 x - 30000 = 0

solvefor x,12x^2+5xy-2y^2=0

so l v e f or x, 12 x^{2} + 5 x y - 2 y^{2} = 0

solvefor a,(b^2)/(c^2)= 1/1-(a^2)/(c^2)

so l v e f or a, \frac{b ^{2}}{c ^{2}} = \frac{1}{1} - \frac{a ^{2}}{c ^{2}}
