Question

Which expression is the factored form of −4.5n+3−4.5n+3 ?

−3(1.5n−1)−3(1.5n−1)


−1.5(−3n+2)−1.5(−3n+2)


−1.5(3n+2)−1.5(3n+2)


−3(1.5n+1)

Answer 1

−3(1.5n−1)−3(1.5n−1)

Explanation:

k12

Answer 2

−3(1.5n−1)−3(1.5n−1)

Explanation:

To factor the expression −4.5n+3−4.5n+3, find the GCF between each term. Using the GCF 3, divide each term by 3 and rewrite it as −3(1.5n−1)−3(1.5n−1).

The other options are not the factors because they give the wrong signs of at least one term in the expression.

−1.5(−3n+2)−1.5(−3n+2) = 4.5n -3 + 4.5n - 3

−1.5(3n+2)−1.5(3n+2) = -4.5n - 3 - 4.5n - 3

−3(1.5n+1) = -4.5n - 3
