1) Find the General Solution to:
(D3 - D2 + D - I)[y] = t5 + 1
2) Prove or disprove that there are two constants A and B such that:
t2D - tD - 8I = (tD + AI)(tD + BI)
The Attempt at a Solution
1) I can't figure out how to attempt this one. Doesn't make sense to me.
2) I should FOIL out the RHS of the equation, but I did that on paper and it didn't make too much sense to me.
