Answer:
x = 1/2 or 2
Step-by-step explanation:
You can factor this as ...
2x^2 -4x -x +2 = 0 . . . rewrite the middle term to enable factoring
2x(x -2) -1(x -2) = 0 . . . . factor by grouping
(2x -1)(x -2) = 0 . . . . factor out (x -2)
x = 1/2, 2 . . . . . . values of x that make the factors zero
Answer:
Step-by-step explanation:
The given expression for water bottles is
.
The highest common factor of all the terms of this expression is .
We now factor to obtain;
Hence the the factorization that represents the number of water bottles and the weight of each bottle is the one in option B.
The correct answer is B
We therefore factor to obtain,
