The expression "5n^2 + 31n - 72" is a quadratic polynomial in terms of the variable ( n ). It can be analyzed using methods such as factoring, completing the square, or applying the quadratic formula to find its roots. If you need specific information about its properties or solutions, please clarify!
√(-10 - 5n2 - 330) = i√(5n2 + 340) = i√[(5(n2 + 68)]
5n2 + 17n + 6 is a quadratic expression. It can be factorised as 5n2 + 17n + 6 = (5n + 2)(n + 3). The expression can be expressed as equal to to a fixed or variable amount when it becomes a function of n. Example : 5n2 + 17n + 6 = 7 or y = 5n2 + 17n + 6
5 * * * * * No. It should be 5n2
(5n + 1)(n + 7)

86. Generated by the cubic t(n) = n3 - 5n2 + 9n - 4 for n = 1, 2, 3, ...
Take 5 out. If the missing signs are pluses, it becomes 5(n2 + 2n + 4) If the missing signs are minuses, it becomes 5(n2 - 2n - 4)
The reaction equation for the oxidation of acetylene (C2H2) with nitrous oxide (N2O) is: 2C2H2 + N2O -> 2CO2 + H2O + N2
There are infinitely many rules that can generate this sequence. As imple one is Un = 5n2 - 21n +72 for n = 1, 2, 3, ... And then n = 4 gives U4 = 68
There are infinitely many possible options. It could, for example, be n to -0.1n5 + n4 - 3.5n3 + 5n2 + 0.6n + 3 for n = 0, 1, 2, ... The simplest, though is n to 3(n + 1)
5n2 + 2n + 6 = 0 is a quadratic equation in the variable n.The equation does not have any real roots. The roots are the complex conjugate pair -0.2 ± 1.077i where i is the imaginary square root of -1.
