21x^3 + 6x^2 - 28x - 8 \\ \\ 3x^2 (7x + 2) - 4(7x + 2) \\ \\ (7x + 2)(3x^2 - 4) \\ \\

The final result is: (7x + 2)(3x<span>² - 4).</span>

Your current schedule only lets you take two 1-credit courses every six months. You need 12 credits to get the degree you want.
lianna [129]
So,

Since you can only take two one-credit courses every six months, you can earn 2 credits every six months, and 4 credits in one year.  Multiplying that by 3, you get 12 credits in 3 years.

It will take 3 years to get the degree.
