What is the coefficient of x^2 in (x^3 + x^2 + x + 1)(x^4 + 3x^3 + 8x + 7x + 1)?

I will assume you meant THIS: 

 (x^3 + x^2 + x + 1)(x^4 + 3x^3 + 8x^2 + 7x + 1)

 

When you multiply the two polynomials you will get these parts :

x^2 * 1     +     x * 7x     +     1 * 8x^2       =     16 x^2 

 

So the coefficient will be ' 16 '
