Answer:
n = ±0.13363
Step-by-step explanation:
2/8 - (14*n*(n))=0 • Use this formula for proof
2/8 = 1/4 A^2 - AB + BA - B^2 =
1/4 - 14n^2 = 0 A^2 - AB + AB - B^2 =
14n^2 = 14n^2 ÷ 1 = 14n^2 • 4 ÷ 4 A^2 - B^2
1 - (14n^2 • 4) ÷ 4 = 1 - 56n^2 ÷ 4
1 - 56n^2 ÷ 4 = 0
1-56n2 ÷ 4 • 4 = 0 • 4
1-56n^2 = 0
56n^2 = 1
n^2 = 1/56 = 0.018
n ≈ ±0.13363
