16x^2-102+44=0

解答

16 x^{2} - 102 + 44 = 0

解答

x = \frac{29}{2 2}, x = - \frac{29}{2 2}

+1

十进制

x = 1.90394 \dots, x = - 1.90394 \dots

求解步骤

16 x^{2} - 102 + 44 = 0

将

102

到右边

16 x^{2} + 44 = 102

将

44

到右边

16 x^{2} = 58

两边除以

16

x^{2} = \frac{29}{8}

对于

x^{2} = f (a)

解为

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

x = \frac{29}{8}, x = - \frac{29}{8}

\frac{29}{8} = \frac{29}{2 2}

- \frac{29}{8} = - \frac{29}{2 2}

x = \frac{29}{2 2}, x = - \frac{29}{2 2}

solvefor x,3x7-4x^2y+xy^3=25

so l v e f or x, 3 x 7 - 4 x^{2} y + x y^{3} = 25

solvefor x,x^2-2(1+3p)x+7(3+2p)=0

so l v e f or x, x^{2} - 2 (1 + 3 p) x + 7 (3 + 2 p) = 0

log_{10}(9)(x^2-4x)=log_{10}(9)(3x-10)

lo g_{10} (9) (x^{2} - 4 x) = lo g_{10} (9) (3 x - 10)
