Question

2. -3n(2n – 5) = 0

a. n = 2 or n = 0
b. n = -5 or n = -3
c. n = 0 or n = 5/2
d. n = 2/5 or n = -3

Answer 1

To find both terms of n, we can divide the factors on one side.

We can divide both sides by (2n - 5) to simplify the equation:


`0 / (2n - 5) = 0`

`-3n = 0`

Divide both sides by -3 to get n by itself:


`n = 0`


We can divide both sides by -3n to simplify the equation:


`0 / -3n = 0`

`2n - 5 = 0`

Add 5 to both sides:


`2n = 5`

Divide both sides by 2 to get n by itself:


`n = (5)/(2)`

The answer is C. n = 0 or n = 5/2.
