To factor 50p2 + 60pq + 18q2, first take out:
A3 as a factor
B2 as a factor
C5 as a factor
D9 as a factor
Answer & Solution
Correct answer: B. 2 as a factor
1. Look at the numbers 50, 60 and 18 together.
2. They share one common factor.
3. Taking out 2 leaves 25p2 + 30pq + 9q2.
4. So the answer is 2 as a factor.
