3t^2-4=0

解答

3 t^{2} - 4 = 0

解答

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

+1

十进制

t = 1.15470 \dots, t = - 1.15470 \dots

求解步骤

3 t^{2} - 4 = 0

将

4

到右边

3 t^{2} = 4

两边除以

3

t^{2} = \frac{4}{3}

对于

x^{2} = f (a)

解为

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

t = \frac{4}{3}, t = - \frac{4}{3}

\frac{4}{3} = \frac{2}{3}

- \frac{4}{3} = - \frac{2}{3}

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

3(-6+x)^2+2(-6)=0

3 (- 6 + x)^{2} + 2 (- 6) = 0

solvefor x,x^2+2x-1=0

so l v e f or x, x^{2} + 2 x - 1 = 0

5/2 x^2-35/6 x+5/3 =0

\frac{5}{2} x^{2} - \frac{35}{6} x + \frac{5}{3} = 0

solvefor x,y^2+xy-x^2=5

so l v e f or x, y^{2} + x y - x^{2} = 5

3x^2-3x-1=x^2+2

3 x^{2} - 3 x - 1 = x^{2} + 2
