x^2-a^2=0

解答

x^{2} - a^{2} = 0

解答

x = a, x = - a

求解步骤

x^{2} - a^{2} = 0

将

a^{2}

到右边

x^{2} = a^{2}

对于

x^{2} = f (a)

解为

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

x = a^{2}, x = - a^{2}

化简

a^{2} : a

化简

- a^{2} : - a

x = a, x = - a

流行的例子

x^{2} = 1 2^{2} + 9^{2}

4 x^{2} = - 10 x + 14

- 2 x^{2} + 3 x - 9 = 0

y^{2} + 4 y + 5 = 3

x^2=sqrt(225)+(sqrt(81))+(2^3+sqrt(16))

x^{2} = 225 + (81) + (2^{3} + 16)
