The GCF is 2n.
4(n + 2)(2n + 5)
It cannot be factored because the discriminant of the quadratic expression is less than zero
The factors are 2n(4n + 3).
3CO2+8N2+4H2O+heat
8n2 - 5n - 11 = 8 8n2 - 5n - 19 = 0 This cannot be factorised so use the quadratic formula: n = [5 +/- sqrt(52 + 4*8*19)]/(2*8) = [5 +/- sqrt(25 + 608)]/16 = [5 +/- sqrt(633)]/16 = [5 +/- sqrt(25.1595)]/16 = -1.25997 or 1.88497
(4n + 1)*(2n + 6) = 8n2 + 26n + 6
8n2+4=12n 8n2-12n+4=0 2n2-3n+1=0 (2n-1)(n-1)=0 2n-1=0 or n-1=0 2n=1 n=1/2 or n=1
55. Fit the cubic t(n) = n3 - 8n2 + 30n - 20
-4n3 + 8n2 - 4n + 7
n3 + 8n2 + 12n = n(n+2)(n+6)
With a suitable choice of the generating rule, any number of your choice can be next.A simple polynomial, though isUn = (n3 - 8n2 + 11n + 36)/2 for n = 1, 2, 3, etc which gives the next number in the sequence as another 8.
we can give the delay function to the faster processing sort we can give the delay function to the faster processing sort
