Question

Khalid carried water bottles to the field to share with his team at halftime. The water bottles weighed

a total of 50x2 + 30x + 10 ounces.
Which factorization could represent the number of water bottles and weight of each water bottle?
A 5 (10x2 + 15x + 2)
B 2 (25x²15x + 5)
C (52 + 2) (102 + 5)
D 10 (5.2² + 3x + 1)

Answer 1

Answer: D

`{50x}^(2) + 30x + 10`

• first factorise out 10:

`= 10(5 {x}^(2) + 3x + 1)`

• then find factors of the quadratic equation in the bracket:
