Answer 1

=x^3+5x^2-2,5x^2-12,5x=x^3+2,5x^2-12,5x

Answer 2

Solving the Equation x(x+5)(x-2.5) = 0

To solve the equation x(x+5)(x-2.5) = 0, we need to find the values of x that make the equation true.

To do this, we can set each factor equal to zero and solve for x.

1. Setting x = 0: - When x = 0, the equation becomes 0(0+5)(0-2.5) = 0 * 5 * (-2.5) = 0. - Therefore, x = 0 is one solution.

2. Setting x + 5 = 0: - When x + 5 = 0, we subtract 5 from both sides to get x = -5. - Substituting x
