((x-3)^2)/(25)+((7-4)^2)/(169)=0

解答

\frac{( x - 3 ) ^{2}}{25} + \frac{( 7 - 4 ) ^{2}}{169} = 0

解答

x = 3 + i \frac{15}{13}, x = 3 - i \frac{15}{13}

求解步骤

\frac{( x - 3 ) ^{2}}{25} + \frac{( 7 - 4 ) ^{2}}{169} = 0

将

\frac{( 7 - 4 ) ^{2}}{169}

到右边

\frac{( x - 3 ) ^{2}}{25} = - \frac{9}{169}

在两边乘以

25

(x - 3)^{2} = - \frac{225}{169}

对于

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

解为

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

解

x - 3 = - \frac{225}{169} : x = 3 + i \frac{15}{13}

解

x - 3 = - - \frac{225}{169} : x = 3 - i \frac{15}{13}

二次方程组的解是:

x = 3 + i \frac{15}{13}, x = 3 - i \frac{15}{13}
