因式分解 p^2+(5p+3)

解答

因式分解

p^{2} + (5 p + 3)

(p - \frac{- 5 + 13}{2}) (p - \frac{- 5 - 13}{2})

求解步骤

p^{2} + (5 p + 3)

去除括号:

(a) = a

= p^{2} + 5 p + 3

解

p^{2} + 5 p + 3 = 0 : p = \frac{- 5 + 13}{2}, p = \frac{- 5 - 13}{2}

多项式因此可因式分解为

= (p - (\frac{- 5 + 13}{2})) (p - (\frac{- 5 - 13}{2}))

整理后得

= (p - \frac{13 - 5}{2}) (p - \frac{- 5 - 13}{2})

f a c t or 2 m x + 4 m y - 3 x - 6 y

f a c t or 4 x + 9 (2^{x}) + 18

f a c t or f (8 x)

f a c t or - \frac{9 - 3 3}{3}

f a c t or x^{2} + 6 x + (p + 3)
