Yes and you can say more x€ (-inf;15)
Answer: 42 months
Explanation: Every month you have deposited $55. $2310 divided by $55 would be 42 months.
(2)^4-2(2)^3-6(2)^2+5
16-64-144+5
-187
We need to multiply the factors (x - 2) and (x^2 + 9x + 10) to see if the product is the original expression given.
(x - 2)(x^2 + 9x + 10)
x^3 + 9x^2 + 10x - 2x^2 - 18x - 20
x^3 + 7x^2 - 8x - 20.
Since the product just found is not the original expression given, Jimmy is wrong.
I will complete the work on paper by synthetic division and post my answer.
After using synthetic division, the correct quotient is x^2 + 9x + 20.
