因式分解 (x+1)^2-8(x+1)+15

解答

因式分解

(x + 1)^{2} - 8 (x + 1) + 15

(x - 2) (x - 4)

求解步骤

(x + 1)^{2} - 8 (x + 1) + 15

乘开

(x + 1)^{2} - 8 (x + 1) + 15 : x^{2} - 6 x + 8

= x^{2} - 6 x + 8

分解

x^{2} - 6 x + 8 : (x - 2) (x - 4)

= (x - 2) (x - 4)

f a c t or (m - n)^{3} - m^{3}

f (a) = a + 4

f a c t or \frac{3}{x ^{2} - 16}

f a c t or 9 x^{8} + 4 8^{7} + 522 x^{6} + 264 x

\frac{d}{d t} ((x) (ln (t)))
