因式分解 1b-1c+1d

解答

因式分解

1 b - 1 c + 1 d

b - c + d

求解步骤

1 \cdot b - 1 \cdot c + 1 \cdot d

因式分解出通项

1

= 1 \cdot (b - c + d)

整理后得

= b + d - c

f a c t or \frac{( 4 )}{( 15 ) π}

f a c t or 23 x + 23 y - b x - b y

f a c t or x^{2} - 6 x + 9

f a c t or 81 x^{1} 2 + 198 x^{6} + 121

f (x) = (cos (x + 1))^{2}
