2.5^2=2^2+x^2

解答

2. 5^{2} = 2^{2} + x^{2}

解答

x = \frac{3}{2}, x = - \frac{3}{2}

+1

十进制

x = 1.5, x = - 1.5

求解步骤

2. 5^{2} = 2^{2} + x^{2}

交换两边

2^{2} + x^{2} = 2. 5^{2}

将

2^{2}

到右边

x^{2} = 2.25

对于

x^{2} = f (a)

解为

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

x = 2.25, x = - 2.25

2.25 = \frac{3}{2}

- 2.25 = - \frac{3}{2}

x = \frac{3}{2}, x = - \frac{3}{2}

solvefor x,4x^2+4y^2-6x+8y+21=0

so l v e f or x, 4 x^{2} + 4 y^{2} - 6 x + 8 y + 21 = 0

x^2+(3m-15)x+12=0

x^{2} + (3 m - 15) x + 12 = 0
