(4x-1)^2=11

解答

(4 x - 1)^{2} = 11

解答

x = \frac{11 + 1}{4}, x = \frac{- 11 + 1}{4}

+1

十进制

x = 1.07915 \dots, x = - 0.57915 \dots

求解步骤

(4 x - 1)^{2} = 11

对于

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

解为

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

解

4 x - 1 = 11 : x = \frac{11 + 1}{4}

解

4 x - 1 = - 11 : x = \frac{- 11 + 1}{4}

二次方程组的解是:

x = \frac{11 + 1}{4}, x = \frac{- 11 + 1}{4}

0.373506=(x^2)/(42.1889*0.2727)

0.373506 = \frac{x ^{2}}{42.1889 \cdot 0.2727}

1/2 w^2-2/3 = 5/6 w

\frac{1}{2} w^{2} - \frac{2}{3} = \frac{5}{6} w

因式分解 x^2+3x-154

f a c t or x^{2} + 3 x - 154

因式分解 3x^2+42x+72

f a c t or 3 x^{2} + 42 x + 72

- 4 < 3 x + 2 \leq 8
