因式分解 x^2-61/26 x-1

解答

因式分解

x^{2} - \frac{61}{26} x - 1

(x - \frac{61 + 5 257}{52}) (x - \frac{61 - 5 257}{52})

求解步骤

x^{2} - \frac{61}{26} x - 1

解

x^{2} - \frac{61 x}{26} - 1 = 0 : x = \frac{61 + 5 257}{52}, x = \frac{61 - 5 257}{52}

多项式因此可因式分解为

= (x - (\frac{61 + 5 257}{52})) (x - (\frac{61 - 5 257}{52}))

整理后得

= (x - \frac{61 + 5 257}{52}) (x - \frac{61 - 5 257}{52})
