因式分解 [(Ar-s)+2][(Ar-s)-2]

解答

因式分解

[(A r - s) + 2] [(A r - s) - 2]

(A r - s + 2) (A r - s - 2)

求解步骤

((A r - s) + 2) ((A r - s) - 2)

去除括号:

(a) = a

= (A r - s + 2) (A r - s - 2)

f a c t or y^{2} - 3 y + 2.25

f a c t or (π) \cdot 2

f a c t or 5 y (8 - 3 z)^{2} - (1 - 5 z)^{2}

f a c t or (x + 2)^{2} - 14

f a c t or 8 m^{2} n^{4} + 4 m^{2} n^{4}
