因式分解 8^2-2x-3

解答

因式分解

8^{2} - 2 x - 3

- 2 x + 61

求解步骤

8^{2} - 2 x - 3

8^{2} = 64

= 64 - 2 x - 3

对同类项分组

= - 2 x + 64 - 3

数字相加/相减:

64 - 3 = 61

= - 2 x + 61

f a c t or ρ z cos (φ) + (- z^{2} sin (2 φ))

f a c t or - 4 sin^{2} (8 x + 2)

f a c t or (9)^{\frac{5}{6}}

f a c t or e^{x^{2} y} + 2 e^{x^{2} y} x^{2} y

f a c t or \frac{24 + 8 2}{7}
