Question

factorize:
9- 30 Z + 25 Z Square ...its urgent...it should be step by step and the answer should be (3-5z)^2

Answer 1

Answer:

solved

Step-by-step explanation:

9- 30 Z + 25 Z Square = 9 - 30 Z + 25 Z² = (3-5z)² = (5z-3)²

the answer can be either (3-5z)² OR  (5z-3)²

Answer 2

25z²- 30z + 9 = 0

25z²-15z-15z +9 = 0

5z(5z-3) -3(5z-3) = 0

(5z-3)(5z-3) = 0

(5z-3)² = 0

or it can be (3-5z)² . in both case we will get same .
