((3c^2))/2 =3(98)

解答

\frac{( 3 c ^{2} )}{2} = 3 (98)

解答

c = 14, c = - 14

求解步骤

\frac{( 3 c ^{2} )}{2} = 3 (98)

去除括号:

(a) = a

\frac{3 c ^{2}}{2} = 3 \cdot 98

数字相乘:

3 \cdot 98 = 294

\frac{3 c ^{2}}{2} = 294

在两边乘以

2

3 c^{2} = 588

两边除以

3

c^{2} = 196

对于

x^{2} = f (a)

解为

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

c = 196, c = - 196

196 = 14

- 196 = - 14

c = 14, c = - 14
