Answer:
Final answer: x=0 m:3 and x=-6 m:2
Step-by-step explanation:
1. 4x³(x²+12x+36)- Divide by greatest common factor, to simplify.
2. 4x³(x+6)(x+6)- Factored
3. 4x³ = 0 Set each factor equal to zero
4. x+6=0 x+6=0
So, x= -6, two times, mulitiplicity 2
So, 4x³=0, so x=0 three times, mulitiplicity 3
Final answer: x=0 m:3 and x=-6 m:2
