A good strategy to start off with this problem in part a is to distribute (x+3)(5x+?) and get 5x^2+?x+15x+3?

#

Now compare this to the left hand side which is 5x^2 + ??x + 3

#

For it to be the same ? Has to be equal to 1

#

And from that information you can combine the x and 15x to get 16x, with 16 being equal to ??
