Answer 2

To solve the equation $(2x - 5)(2x - 9)(0.3x - 12) = 0$, you can use the zero-product property, which states that if the product of two or more factors is equal to zero, then at least one of the factors must be equal to zero.

So, set each factor equal to zero and solve for $x$:

1. $2x - 5 = 0$: Add 5 to both sides: $2x = 5$ Divide by 2: $x = \frac{5}{2}$

2. $2x - 9 = 0$: Add 9 to both sides: $2x = 9$ Divide by 2: $x = \frac{9}{2}$

3. $0.3x - 12 = 0$: Add 12 to both sides: $0.3x = 12$ Divide by 0.3 (which is the same as multiplying by 10/3): $x = \frac{12}{0.3} = 40$

So, the solutions to the equation are $x = \frac{5}{2}$, $x = \frac{9}{2}$, and $x = 40$.
