解答

(7 x + 4)^{2} = 4

解答

x = - \frac{2}{7}, x = - \frac{6}{7}

+1

十进制

x = - 0.28571 \dots, x = - 0.85714 \dots

求解步骤

(7 x + 4)^{2} = 4

对于

(g (x))^{2} = f (a)

解为

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

解

7 x + 4 = 4 : x = - \frac{2}{7}

解

7 x + 4 = - 4 : x = - \frac{6}{7}

二次方程组的解是:

x = - \frac{2}{7}, x = - \frac{6}{7}

(2x-7)/3 =5-(3x-2)/4

\frac{2 x - 7}{3} = 5 - \frac{3 x - 2}{4}

化简-1/8+5/6-5/12

s im pl i f y - \frac{1}{8} + \frac{5}{6} - \frac{5}{12}

化简 1000^{2/3}

s im pl i f y 100 0^{\frac{2}{3}}

x^2+x^2=(x+3)^2

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