Answer 3

To solve the given equations, we need to find the values of x that make each equation equal to zero. To do that, we'll set each factor to zero and solve for x.

1. (x + 1.2)(x + 5)(x - 10) = 0

The equation has three factors: (x + 1.2), (x + 5), and (x - 10). For the entire equation to equal zero, at least one of these factors must be equal to zero.

Setting each factor to zero:

a) x + 1.2 = 0 x = -1.2

b) x + 5 = 0 x = -5

c) x - 10 = 0 x = 10

So, the solutions to the equation are x = -1.2, x = -5, and x = 10.

2. (x + 1)(x - 2) = 0

Similarly, we have two factors: (x + 1) and (x - 2). For the entire equation to equal zero, at least one of these factors must be equal to zero.

Setting each factor to zero:

a) x + 1 = 0 x = -1

b) x - 2 = 0 x = 2

So, the solutions to the equation are x = -1 and x = 2.
