The first one is not easy unless you know what is going on

The degree of the remainder is at most 1 lower than the degree of the divisor. So it isn't always going to be 1 lower.
Sometimes there is no coefficient of x. In this case assuming that the form ax + b works since if it was actually two degrees lower, the remainders would be the same for both cases. It may not work for other questions and it is best to not assume so

Should be ok I think, because if indeed the remainder does not contain x then a = 0.
But in this case a definitely cannot be zero since the remainders when divided by both numbers are different.

thankyou so much!
