Acity's population in 2000 was 152,920. if the population increases at an annual rate of 11 percent, when will the population reach 500,000?

the equation given is y = a(1 ± r)^t

Talia grouped the terms and factored out the gcf of the groups of the polynomial 15x2 – 3x – 20x + 4. her work is shown below. (15x2 – 3x) + (–20x + 4) 3x(5x – 1) + 4(–5x + 1) talia noticed that she does not have a common factor. what should she do?
