因式分解 (2x-1)^2-5(2x-1)-6

解答

因式分解

(2 x - 1)^{2} - 5 (2 x - 1) - 6

2 x (2 x - 7)

求解步骤

(2 x - 1)^{2} - 5 (2 x - 1) - 6

乘开

(2 x - 1)^{2} - 5 (2 x - 1) - 6 : 4 x^{2} - 14 x

= 4 x^{2} - 14 x

分解

4 x^{2} - 14 x : 2 x (2 x - 7)

= 2 x (2 x - 7)

f a c t or e^{3} - 8

f a c t or ab - 2 b + a d - 2 d

f (t) = e^{12 t} (sin (12 t))^{2}

f a c t or 1.2 (\frac{15 - F}{1.5})

f a c t or 23 i - 23 i + 4
