Question

divide z(5z2+20z) by 5z (z+4) plss
​

Answer 1

Answer:

z

Step-by-step explanation:

z(5z²+20z)/5z(z+4)

5z²(z+4)/5z(z+4)

z

Answer 2

Answer:

z

Step-by-step explanation:

$\frac{z(5 {z}^{2} + 20z) }{5z(z + 4)} \\ \\ = \frac{z \times 5z(z + 4)}{5z(z + 4)} \\ \\ = \frac{5 {z}^{2} (z + 4)}{5z(z + 4)} \\ \\ = \frac{5 {z}^{2} ( \cancel{z + 4})}{5z( \cancel{z + 4})} \\ \\ = \frac{5 {z}^{2} }{5z} \\ \\ = \frac{ \cancel 5 {z}^{2} }{ \cancel 5z} \\ \\ = \frac{ {z}^{2} }{z} \\ \\ = {z}^{2 - 1} \\ \\ = \underline{ \underline{ z}}$
