因式分解 (a^2-b^2-c^2)-4b^2c^2

解答

因式分解

(a^{2} - b^{2} - c^{2}) - 4 b^{2} c^{2}

a^{2} - b^{2} - c^{2} - 4 b^{2} c^{2}

求解步骤

(a^{2} - b^{2} - c^{2}) - 4 b^{2} c^{2}

去除括号:

(a) = a

= a^{2} - b^{2} - c^{2} - 4 b^{2} c^{2}

f a c t or p^{2} + 10 p + 21

f a c t or y^{2} - 9

b - 3.9 = 3.21

3 x^{2} + 5 x = 0

s im pl i f y (- 9)^{\frac{1}{2}}
