Q. Solve

3 n^{2}=9 n

.

Subtract $9n$ : First, let's subtract $9n$ from both sides to set the equation to zero. $\newline$ $3n^2 - 9n = 0$
Factor out $3n$ : Now, we can factor out a common factor of $3n$ . $3n(n - 3) = 0$
Set factors equal to zero: Next, we set each factor equal to zero and solve for $n$ . $\newline$ For $3n = 0$ , we get $n = 0$ . $\newline$ For $n - 3 = 0$ , we get $n = 3$ .
