因式分解 4(x-5)^2+3(x-5)

解答

因式分解

4 (x - 5)^{2} + 3 (x - 5)

(x - 5) (4 x - 17)

求解步骤

4 (x - 5)^{2} + 3 (x - 5)

因式分解出通项

(x - 5) : (x - 5) (4 (x - 5) + 3)

= (x - 5) (4 (x - 5) + 3)

4 (x - 5) + 3 : 4 x - 17

= (x - 5) (4 x - 17)

\frac{5}{17} = \frac{y}{11}

- \frac{2}{5} d + 60 = 0

s im pl i f y (\frac{x ^{3}}{y ^{3}})^{- 3}

4 x + 8 \cdot 4 = 48
