簡約 (3-sqrt(4-x))^2

解

簡約

(3 - 4 - x)^{2}

- x - 6 4 - x + 13

解答ステップ

(3 - 4 - x)^{2}

完全平方式を適用する:

(a - b)^{2} = a^{2} - 2 ab + b^{2}

(3 - 4 - x)^{2} = 3^{2} - 2 \cdot 3 4 - x + (4 - x)^{2}

= 3^{2} - 2 \cdot 3 4 - x + (4 - x)^{2}

簡素化

3^{2} - 2 \cdot 3 4 - x + (4 - x)^{2} : - x - 6 4 - x + 13

= - x - 6 4 - x + 13

e x p an d (T - a) (T - b) (T - d) (T - e) (T - f)

e x p an d (2 x^{2} - 5 x + 6) l e f t (3 x^{4} - 5 x^{3} - 6 x^{2} + 4 x - 3)

e x p an d \frac{2 s}{( s ^{2} + 36 ) ( s - 1 )}

\frac{d}{d t} ((w (t, x (w, t), y (w, t), z (w, t))) (x (w, t)^{2} + y (w, t)^{2} + z (w, t)^{2}))

e x p an d lo g_{2} (3 \frac{x + 2}{4 x + 5})
