Answer 2

To solve the given equation:

(4y - 2)(14 + 21)(1.8 - 0.3y) = 0

We 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 zero. So, in this case, we can set each factor equal to zero and solve for y:

4y - 2 = 0 or 14 + 21 = 0 or 1.8 - 0.3y = 0

Solving each equation, we get:

4y - 2 = 0 4y = 2 y = 1/2

14 + 21 = 0 (this equation has no solution since the sum of two positive numbers cannot be zero)

1.8 - 0.3y = 0 0.3y = 1.8 y = 6

Therefore, the solutions to the given equation are y = 1/2 and y = 6.
