QuestionConsider the following polynomial inequality. x2(x+6)(x3)>0x^{2}(x+6)(x-3)>0
Step 1 of 2 : Write the polynomial inequality in the form p(x)<0,p(x)0,p(x)>0p(x)<0, p(x) \leq 0, p(x)>0, or p(x)0p(x) \geq 0; then find the real zeros of p(x)p(x).

Studdy Solution
To find the real zeros of p(x)=x2(x+6)(x3) p(x) = x^2(x+6)(x-3) , we set p(x)=0 p(x) = 0 and solve for x x :
x2(x+6)(x3)=0 x^2(x+6)(x-3) = 0
This equation is satisfied when any of the factors is zero:
1. x2=0 x^2 = 0 gives x=0 x = 0 .
2. x+6=0 x+6 = 0 gives x=6 x = -6 .
3. x3=0 x-3 = 0 gives x=3 x = 3 .

Thus, the real zeros of p(x) p(x) are x=0,6,3 x = 0, -6, 3 .
The real zeros of the polynomial are x=0,6,3 x = 0, -6, 3 .
