因式分解 (6x-1)+(-x^2)

解答

因式分解

(6 x - 1) + (- x^{2})

- (x - 3 - 22) (x - 3 + 22)

求解步骤

(6 x - 1) + (- x^{2})

去除括号:

(a) = a

= 6 x - 1 - x^{2}

因式分解出通项

- 1

= - (x^{2} - 6 x + 1)

分解

x^{2} - 6 x + 1 : (x - 3 - 22) (x + - 3 + 22)

= - (x - 3 - 22) (x + - 3 + 22)

f a c t or (x^{- 1} + y^{- 1})^{2}

f a c t or a^{4} + 6^{2} + 1

f a c t or (x^{2} y^{4}) 2

f a c t or (x - y)^{3} - 8

f a c t or (8 + x) (x + 2) - 2 x
