solvefor b,19a^2+22b^2=43a^2b^2

解

解く

b, 19 a^{2} + 22 b^{2} = 43 a^{2} b^{2}

解

b = i \frac{19 a 22 - 43 a ^{2}}{22 - 43 a ^{2}}, b = - i \frac{19 a 22 - 43 a ^{2}}{22 - 43 a ^{2}}; a \neq = \frac{22}{43}, a \neq = - \frac{22}{43}

解答ステップ

19 a^{2} + 22 b^{2} = 43 a^{2} b^{2}

19 a^{2}

を右側に移動します

22 b^{2} = 43 a^{2} b^{2} - 19 a^{2}

43 a^{2} b^{2}

を左側に移動します

22 b^{2} - 43 a^{2} b^{2} = - 19 a^{2}

因数

22 b^{2} - 43 a^{2} b^{2} : b^{2} (22 - 43 a^{2})

b^{2} (22 - 43 a^{2}) = - 19 a^{2}

以下で両辺を割る

22 - 43 a^{2}; a \neq = \frac{22}{43}, a \neq = - \frac{22}{43}

b^{2} = - \frac{19 a ^{2}}{22 - 43 a ^{2}}; a \neq = \frac{22}{43}, a \neq = - \frac{22}{43}

x^{2} = f (a)

の場合, 解は

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

b = - \frac{19 a ^{2}}{22 - 43 a ^{2}}, b = - - \frac{19 a ^{2}}{22 - 43 a ^{2}}; a \neq = \frac{22}{43}, a \neq = - \frac{22}{43}

簡素化

- \frac{19 a ^{2}}{22 - 43 a ^{2}} : i \frac{19 a 22 - 43 a ^{2}}{22 - 43 a ^{2}}

簡素化

- - \frac{19 a ^{2}}{22 - 43 a ^{2}} : - i \frac{19 a 22 - 43 a ^{2}}{22 - 43 a ^{2}}

b = i \frac{19 a 22 - 43 a ^{2}}{22 - 43 a ^{2}}, b = - i \frac{19 a 22 - 43 a ^{2}}{22 - 43 a ^{2}}; a \neq = \frac{22}{43}, a \neq = - \frac{22}{43}
