受欢迎的代数 >

(y^2)/3 =(y^2)/6+2

解答

\frac{y ^{2}}{3} = \frac{y ^{2}}{6} + 2

解答

y = 23, y = - 23

+1

十进制

y = 3.46410 \dots, y = - 3.46410 \dots

求解步骤

\frac{y ^{2}}{3} = \frac{y ^{2}}{6} + 2

将

\frac{y ^{2}}{6}

para o lado esquerdo

\frac{y ^{2}}{6} = 2

在两边乘以

6

y^{2} = 12

对于

x^{2} = f (a)

解为

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

y = 12, y = - 12

12 = 23

- 12 = - 23

y = 23, y = - 23

(3x+5)^2+5(3x+5)+6=0

(3 x + 5)^{2} + 5 (3 x + 5) + 6 = 0

-5c^2+c-18=-6c^2

- 5 c^{2} + c - 18 = - 6 c^{2}

(2x-1)(x+2)=(x+3)(x+1)

(2 x - 1) (x + 2) = (x + 3) (x + 1)

y^{2} - 2 y - 1 = 0

(x + 12)^{2} = 9
