(-(1-0)^2)/(2(1^2))

解答

\frac{- ( 1 - 0 ) ^{2}}{2 ( 1 ^{2} )}

- \frac{1}{2}

十进制

- 0.5

求解步骤

\frac{- ( 1 - 0 ) ^{2}}{2 ( 1 ^{2} )}

解

- (1 - 0)^{2} : - 1

解

2 (1^{2}) : 2

= \frac{- 1}{2}

使用分式法则:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{1}{2}

\frac{7 ^{2}}{3 ^{2} - 2}

3 z^{2} + z + 3 = 0

f a c t or 5 x^{2} + 14 x y + 8 y^{2}

6 (2 x + 4)^{2} = (2 x + 4) + 2

f a c t or 2 x^{3} - x^{2} + 50 x - 25
