Solving quadratic equations by factoring

m (m-3) = 0

Because it has already been factored, we can solve it straight away. Now, since m is a variable, we yield the same result if m = 0 or m = 3 because we have two components to this equation.

We can either have m = 0 or m - 3 = 0

Hence, m is either 0 or 3
