Which equations have the same pair of solutions? Select all that apply. n(n + 3)(n - 4) = 0 2n(4n + 6)(6n - 4) = 0 0 = 2n(6 - 4n)(4 - 6n) 0 = n(2n + 3)(3n - 2) 2n(2n + 3)(3n - 2) = 0 3n(6n + 9)(9n - 6) = 0

Answer:

2, 4, 5, and 6 have the same pair of solutions.

Explanation:

1. n(n+3)(n-4) = 0

2. 2n(4n+6)(6n-4) = 0

3. 2n(6-4n)(4n-6n) = 0

4. n(2n+3)(3n-2) = 0

5. 2n(2n+3)(3n-2) = 0

6. 3n(6n+9)(9n-6) = 0

Answers:

1. n = 0, -3, 4

2. n = 0, -3/2, 2/3

3. n = 0, 3/2

4. n = 0, -3/2, 2/3

5. n = 0, -3/2, 2/3

6. n = 0, -3/2, 2/3

Answer:

2,4,5,6

Explanation:


n=0,4n+6=0\implies n=-(6)/(4)=-(3)/(2)


6n-4=0\implies n=(4)/(6)=(2)/(3)

n=0,
n=-(3)/(2),n=(2)/(3)

3.
2n(6n-4)(4-6n)=0

n=0


6n-4=0


n=(4)/(6)=(2)/(3)


4-6n=0


n=(4)/(6)=(2)/(3)

4.
n(2n+3)(3n-2)=0


n=0


2n+3=0


n=-(3)/(2)


3n-2=0


n=(2)/(3)

5.
2n(2n+3)(3n-2)=0


n=0


2n+3=0


n=-(3)/(2)


3n-2=0


n=(2)/(3)

6.
3n(6n+9)(9n-6)=0


n=0


6n+9=0


n=(-9)/(6)=-(3)/(2)


9n-6=0


n=(6)/(9)=(2)/(3)

Answer:2,4,5 and 6 equation have same solutions.
