Answer:
F. 20(3a-10)^2
Please give me brainliest
Step-by-step explanation:
180a^2-1200a+2000
Start by looking for a common factor: In this case, it's 20
From here, divide 20 from every number
180a^2/20= 9a^2
1200a/20= 60a
2000/20= 100
You end up with:
20(9a^2-60a+100)
But you can still simplify (9a^2-60a+100)
(9a^2-60a+100) simplifies to (3a-10)^2
So the answer is:
20(3a-10)^2
