The factors are 2n(4n + 3).
fractions equivalent for 12 = 12/1, 24/2, 36/3,...
36/12 = 3 12/36 = 1/3
1/3 + 3/4= (4 + 3)/12= 7/12
equivalent fractions of 2/3 = 4/6, 6/9, 8/12...
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
n3 + 3n2 + 4n + 12 = (n3 + 3n2) + (4n + 12) = n2(n + 3) + 4(n + 3) = (n2 + 4)(n + 3).
4n+13=1 -13 -134n=-12/4 /4n=-3
4n + 9 = -3 Now, we take away 9 from both sides 4n = -12 Now divide by 4 n = -3
Subtracting 3n from each side gives 12 = 4n or 4n = 12. n = 12/4 n = 3

3 + 3n = 9 + 2n + 4n n = -2
N=3.
4n + 3 = 31n 3 = 27n n = 3/27
6n -3=2n+9 6n-2n=9+3 4n=12 n=12/4 n=3
4n + 3 = 19Subtract 3 from each side:4n = 16Divide each side by 4:n = 4
