Answer 2

To find the solutions for the given equation, you need to set the entire expression equal to zero and then solve for 'x'. So the equation is:

(-18x - 3) * (-3x + 7.5) = 0

Now, since the product of two factors is zero, at least one of the factors must be zero. So, set each factor equal to zero and solve for 'x':

1. -18x - 3 = 0 Add 3 to both sides: -18x = 3 Divide by -18: x = 3 / -18 x = -1/6

2. -3x + 7.5 = 0 Subtract 7.5 from both sides: -3x = -7.5 Divide by -3: x = -7.5 / -3 x = 2.5

The solutions for 'x' are x = -1/6 and x = 2.5.
