The projected population in thousands for a city over the next several years can be estimated by the function P(x)= x^3 + 2x^2 - 8x + 520, where x is the number of years since 2005. Use synthetic substitution to estimate the population.

Question

Also could anyone help me with the difference of squares for example 18x^3+9x^2-2x-1;2x+1. once i divide out the 2 i don't know what to do with the fractions.

Answer 1

18x^3+9x^2 - (2x+1)
9x^2(2x+1) - (2x+1)
(9x^2-1)(2x+1)
(3x+1)(3x-1)(2x+1)
