(6a+2)(8a+7)=0

解答

(6 a + 2) (8 a + 7) = 0

解答

a = - \frac{1}{3}, a = - \frac{7}{8}

+1

十进制

a = - 0.33333 \dots, a = - 0.875

求解步骤

(6 a + 2) (8 a + 7) = 0

使用零因数法则： If

ab = 0

then

a = 0

or

b = 0

6 a + 2 = 0 or 8 a + 7 = 0

解

6 a + 2 = 0 : a = - \frac{1}{3}

解

8 a + 7 = 0 : a = - \frac{7}{8}

二次方程组的解是:

a = - \frac{1}{3}, a = - \frac{7}{8}
