1/2+x*x= 4/3

解答

\frac{1}{2} + x \cdot x = \frac{4}{3}

解答

x = \frac{5}{6}, x = - \frac{5}{6}

+1

十进制

x = 0.91287 \dots, x = - 0.91287 \dots

求解步骤

\frac{1}{2} + xx = \frac{4}{3}

将

\frac{1}{2}

到右边

xx = \frac{4}{3} - \frac{1}{2}

化简

x^{2} = \frac{4}{3} - \frac{1}{2}

对于

x^{2} = f (a)

解为

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

x = \frac{4}{3} - \frac{1}{2}, x = - \frac{4}{3} - \frac{1}{2}

\frac{4}{3} - \frac{1}{2} = \frac{5}{6}

- \frac{4}{3} - \frac{1}{2} = - \frac{5}{6}

x = \frac{5}{6}, x = - \frac{5}{6}

solvefor x,szlsf=x^2+2xy+3y^2-4x-3y

so l v e f or x, sz l s f = x^{2} + 2 x y + 3 y^{2} - 4 x - 3 y

solvefor x,3x^2+30x+50=0

so l v e f or x, 3 x^{2} + 30 x + 50 = 0

solvefor x,x^2y=1+cx

so l v e f or x, x^{2} y = 1 + c x

5 x (x - 2) = 15

(3x+2)(4x-5)=-11

(3 x + 2) (4 x - 5) = - 11
