64x^2-144=-23

解答

64 x^{2} - 144 = - 23

解答

x = \frac{11}{8}, x = - \frac{11}{8}

+1

十进制

x = 1.375, x = - 1.375

求解步骤

64 x^{2} - 144 = - 23

将

144

到右边

64 x^{2} = 121

两边除以

64

x^{2} = \frac{121}{64}

对于

x^{2} = f (a)

解为

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

x = \frac{121}{64}, x = - \frac{121}{64}

\frac{121}{64} = \frac{11}{8}

- \frac{121}{64} = - \frac{11}{8}

x = \frac{11}{8}, x = - \frac{11}{8}

solvefor y,(3y^2)/2 =x^2+x+c

so l v e f or y, \frac{3 y ^{2}}{2} = x^{2} + x + c

3 x^{2} + 7 x - 49 = 0

solvefor x,(x-y)^2+xy=1

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

solvefor x,x^2+xy-y^2=16

so l v e f or x, x^{2} + x y - y^{2} = 16
