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

x(x + 3)(x + 3) = 0

<=> x(x + 3)^2 = 0

<=> x = 0

      (x + 3)^2 = 0

<=> x = 0

     x + 3 = 0

<=> x = 0

     x = -3

=> S = {0; - 3}

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."

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
