5x^2-2=3-3x^2

解答

5 x^{2} - 2 = 3 - 3 x^{2}

解答

x = \frac{5}{2 2}, x = - \frac{5}{2 2}

+1

十进制

x = 0.79056 \dots, x = - 0.79056 \dots

求解步骤

5 x^{2} - 2 = 3 - 3 x^{2}

将

2

到右边

5 x^{2} = - 3 x^{2} + 5

将

3 x^{2}

para o lado esquerdo

8 x^{2} = 5

两边除以

8

x^{2} = \frac{5}{8}

对于

x^{2} = f (a)

解为

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

x = \frac{5}{8}, x = - \frac{5}{8}

\frac{5}{8} = \frac{5}{2 2}

- \frac{5}{8} = - \frac{5}{2 2}

x = \frac{5}{2 2}, x = - \frac{5}{2 2}

流行的例子

a^{2} + 4 = 13 + 7

- x^{2} - 2 x + 10 = 0

solvefor x,f(a+1)=4x^2-x+4

so l v e f or x, f (a + 1) = 4 x^{2} - x + 4

solvefor x,x^2-6x-19=0

so l v e f or x, x^{2} - 6 x - 19 = 0

4 x^{2} - 16 = 32
