因式分解 (7h+1)+7h^2

解答

因式分解

(7 h + 1) + 7 h^{2}

7 h - \frac{- 1 + \frac{3}{7}}{2} h - \frac{- 1 - \frac{3}{7}}{2}

求解步骤

(7 h + 1) + 7 h^{2}

去除括号:

(a) = a

= 7 h + 1 + 7 h^{2}

改写为

= 7 (h^{2} + h + \frac{1}{7})

因式分解

h^{2} + h + \frac{1}{7} : h - \frac{\frac{3}{7} - 1}{2} h - \frac{- \frac{3}{7} - 1}{2}

7 h - \frac{\frac{3}{7} - 1}{2} h - \frac{- \frac{3}{7} - 1}{2}
