Question

Plz help me and explain **Solve the equation: x(x+3)(x+3)=0

Answer 1

Answer:

three solutions:  {-3, -3, 0}

Step-by-step explanation:

This polynomial has already been factored, and the factors are x, x + 3 and x = +3.  To solve this equation, set each of the factors equal to zero separately and solve each of the resulting equations:

x = 0 is a solution; the given equation equals zero when x = 0.

The next factor is x + 3; setting this equal to 0 yields the solution x = -3.

The last factor is x + 3; x = -3 is the third solution.

In summary, (x + 3)(x = 3) = 0 has two solutions; we call them "repeated roots."    x(x + 3)(x = 3) = 0 has three solutions:  {-3, -3, 0} of which two are "repeated."
