1) 1/2
2) 7/8
3) 4
4) 19/8 = 2 3/8
Factor the polynomial:
4u² – 20u + 25
Rewrite – 20u as – 10u – 10u, and then factor it by grouping:
= 4u² – 10u – 10u + 25
= 2u * (2u – 5) – 5 * (2u – 5)
= (2u – 5) * (2u – 5)
= (2u – 5)² <––– this is the answer.
I hope this helps. =)
They definitely can be positive they can be negative and they can have an absolute value but I would choose they both can be positive and negative
