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

(5n + 1)(n + 7)

√(-10 - 5n2 - 330) = i√(5n2 + 340) = i√[(5(n2 + 68)]

5 * * * * * No. It should be 5n2

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 Â± 1.077i where i is the imaginary square root of -1.

CH=CH + 5N2O -----> 5N2 + 2CO2 + H2O

A molar ratio is the ratio of any two coefficients in a stoichiometric equation. So in this case, there are six possible combinations. 4:6, 4:5, 4:6, 6:5, 6:6, 5:6.

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)

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
