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:

$0 \div (2n - 5) = 0$
$-3n = 0$

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

$n = 0$


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

$0 \div -3n = 0$
$2n - 5 = 0$

Add 5 to both sides:

$2n = 5$

Divide both sides by 2 to get n by itself:

$n = \frac{5}{2}$

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