(4x-3)^2-16x^2=9-24x

解答

(4 x - 3)^{2} - 16 x^{2} = 9 - 24 x

对所有 x 为真

求解步骤

(4 x - 3)^{2} - 16 x^{2} = 9 - 24 x

展开

(4 x - 3)^{2} - 16 x^{2} : - 24 x + 9

- 24 x + 9 = 9 - 24 x

将

9

到右边

- 24 x = - 24 x

将

24 x

para o lado esquerdo

0 = 0

两侧相等

对所有 x 为真

57 + (3032 \cdot \frac{325 - 27 \cdot a}{644}) - 942 \cdot a = 0

\frac{7 + 4 x}{9} = \frac{x}{2}

so l v e f or s, - 77 = 11 u + 99

\frac{7}{3} x + \frac{6}{3} x = \frac{6}{2} x + \frac{3}{2} x + 8

x = lo g_{3} (53)
