2NH4NO3->2N2+O2+4H2O
n * 2n = 2n2
2n2 / n = 2n
2(n2+3n-54) 2(n+9)(n-6)
If the question is, "What is the solution to 2n2 + 6n - 108 = 0 ?"The equation can be factored : 2n2 + 6n - 108 = (2n - 12)(n + 9) = 0If 2n -12 = 0 then n = 6If n + 9 = 0 then n = -9The roots of this equation are n = 6 and n = -9.
