I was wondering If i would be able to get help with these last questions:
a) Prove by showing all steps of working that 3^(x+2)+27 / 5 x 3^x + 15 can be simplified to 9 / 5
a) p ( x) = ax^3 + bx^2 - 5x + c is a polynomial exactly divisible by (x+2).
Also p(0) = p (1) = -6, find a, b and c and completely factorize p (x).
Any Contribution will be appreciated!
