16p^2-9=0

解答

16 p^{2} - 9 = 0

解答

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

+1

十进制

p = 0.75, p = - 0.75

求解步骤

16 p^{2} - 9 = 0

将

9

到右边

16 p^{2} = 9

两边除以

16

p^{2} = \frac{9}{16}

对于

x^{2} = f (a)

解为

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

p = \frac{9}{16}, p = - \frac{9}{16}

\frac{9}{16} = \frac{3}{4}

- \frac{9}{16} = - \frac{3}{4}

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

x^{2} + 12 x + 100 = 0

6 x^{2} + 96 = 0

solvefor x,3(13x^2-4y^2)=15y^2-2x^2

so l v e f or x, 3 (13 x^{2} - 4 y^{2}) = 15 y^{2} - 2 x^{2}

u^{2} + 6 u + 5 = 0
