Question

7n^2-2n=0
Factors and the values of n​

Answer 1

Answer: Factors to n(7n-2)=0, solutions are 0, 2/7.

Step-by-step explanation: So, we have 7n^2-2n=0. We want to factor it, so we look at what the two terms have in common. 7 and 2 don't have any common factors, but both have an n. So, if we pull out an n, we have n(7n-2). So right away, we know one of our values for n is 0. The other one is the solution to the equation 7n-2=0, so 7n=2, n=2/7.

Answer 2

Answer: Factors to n(7n-2)=0, solutions are 0, 2/7.

Step-by-step explanation: 7n^2-2n=0. We want to factor it, so we look at what the two terms have in common. 7 and 2 don't have any common factors, but both have an n.
