1^2=m^2+(-3/2)^2

解答

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

解答

m = \frac{5}{2} i, m = - \frac{5}{2} i

求解步骤

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

展开

1^{2} : 1

展开

m^{2} + (- \frac{3}{2})^{2} : m^{2} + \frac{9}{4}

1 = m^{2} + \frac{9}{4}

交换两边

m^{2} + \frac{9}{4} = 1

将

\frac{9}{4}

到右边

m^{2} = 1 - \frac{9}{4}

化简

1 - \frac{9}{4} : - \frac{5}{4}

对于

x^{2} = f (a)

解为

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

m = - \frac{5}{4}, m = - - \frac{5}{4}

- \frac{5}{4} = \frac{5}{2} i

- - \frac{5}{4} = - \frac{5}{2} i

m = \frac{5}{2} i, m = - \frac{5}{2} i

流行的例子

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

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

0 = x^{2} + 6 x

completesquare x^2+x-4=0

co m pl e t es q u a re x^{2} + x - 4 = 0

5 x^{2} - 2 x - 39 = 0

- 3 (x + 5)^{2} - 4 = 77
