solvefor x,x^2+1=y^2+1

解答

求解

x, x^{2} + 1 = y^{2} + 1

解答

x = y, x = - y

求解步骤

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

将

1

到右边

x^{2} = y^{2}

对于

x^{2} = f (a)

解为

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

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

化简

y^{2} : y

化简

- y^{2} : - y

x = y, x = - y

29.9-0.0031x^2=0

29.9 - 0.0031 x^{2} = 0

2(2x^2-5)=3(2-3x^2),4x^2-3=6-3x^2

2 (2 x^{2} - 5) = 3 (2 - 3 x^{2}), 4 x^{2} - 3 = 6 - 3 x^{2}

14 = (2 x - 3)^{2} - 2

x^{2} - 0.3 x - 0.7 = 0

2 r^{2} - r - 4 = 0
