Question

if N is a positive integer, and twice the square of n is the same as four times and, what is the value of n?​

Answer 1

First translate into an equation. Then solve

N=non-negative integers.

2(n^2) = 4n. Divide both sides of = by 2
n^2 = 2n subtract 2n from both sides
n^2 - 2n = 0. Factor
n(n - 2) =0. Solve factor = 0.
N = 0. N-2= 0
+2. +2
N= 2

So 0 & 2 are both answers
