因式分解 [(m-4)+n][(m-4)-n]

解答

因式分解

[(m - 4) + n] [(m - 4) - n]

(m - 4 + n) (m - 4 - n)

求解步骤

((m - 4) + n) ((m - 4) - n)

去除括号:

(a) = a

= (m - 4 + n) (m - 4 - n)

f a c t or sin^{4} (x) - cos^{4 x} (x)

f a c t or (7 d^{3} - 4) + (- 8 d^{2} + 3 d)

f a c t or 16 a^{2} + 2 a^{2} π

f a c t or 3 (a)^{2} - (a) + 5

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