Answer 2

To solve the equation (4y - 12)(2.1 + 0.3y) = 0, you can use the zero-product property, which states that if the product of two factors is equal to zero, then at least one of the factors must be equal to zero.

So, in this case, you have two factors:

1. 4y - 12
2. 2.1 + 0.3y

Set each factor equal to zero and solve for y:

1. 4y - 12 = 0 Add 12 to both sides: 4y = 12 Divide both sides by 4: y = 12/4 y = 3

2. 2.1 + 0.3y = 0 Subtract 2.1 from both sides: 0.3y = -2.1 Divide both sides by 0.3: y = -2.1 / 0.3 y = -7

So, there are two solutions for y:

1. y = 3
2. y = -7
