化简-x^{(3)}+4xy-2y^{(2)}+4x+1

解答

化简

- x^{(3)} + 4 x y - 2 y^{(2)} + 4 x + 1

- x^{3} + 4 x y - 2 y^{2} + 4 x + 1

求解步骤

- x^{(3)} + 4 x y - 2 y^{(2)} + 4 x + 1

去除括号:

(a) = a

= - x^{3} + 4 x y - 2 y^{2} + 4 x + 1

f a c t or 3 y^{2} - 2 a x + 3 x - 2 a y^{2} + 4 a - 6

f a c t or a x - 2 a y - 6 b y + 3 b x

f a c t or \frac{6}{4}

f a c t or 2^{- 2}

f a c t or \frac{x ^{2}}{x ^{2} - 1}
