Answer:
9(5x−19)(x−4)
Step-by-step explanation:
First you have to distribute
45x^2+−360x+720+(9)(x)+(9)(−4)
45x^2+−360x+720+9x+−36
Then you have to combine like terms
45x^2+−360x+720+9x+−36
(45x^2)+9-360+9x)+(720+-36)
45x^2−351x+684
9(5x−19)(x−4)
Hope this helped!
Answer:
9(x-4) [5x-19]
Step-by-step explanation:
45(x-4)^2+9(x-4)
We can factor out a 9 (x-4)
9 (x-4) [5(x-4) +1)]
Distribute in side the parentheses
9(x-4) [5x-20+1]
9(x-4) [5x-19]
