3s^2+2=-62

解答

3 s^{2} + 2 = - 62

解答

s = \frac{8}{3} i, s = - \frac{8}{3} i

求解步骤

3 s^{2} + 2 = - 62

将

2

到右边

3 s^{2} = - 64

两边除以

3

s^{2} = - \frac{64}{3}

对于

x^{2} = f (a)

解为

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

s = - \frac{64}{3}, s = - - \frac{64}{3}

- \frac{64}{3} = \frac{8}{3} i

- - \frac{64}{3} = - \frac{8}{3} i

s = \frac{8}{3} i, s = - \frac{8}{3} i

solvefor t,s=-16t^2+96t+112

so l v e f or t, s = - 16 t^{2} + 96 t + 112

6 x^{2} + 16 x - 22 = 0

(x^{2} + 3 x + 2) = 0

a^{2} + 9^{2} = 1 2^{2}

x^{2} + 10 x = 1
