The polynomial p(x) has leading coefficient a and degree m, and the polynomial q(x) has leading coefficient b and degree n. Suppose the m>n, what is the leading coefficient and degree of px+q(x)?

a) Leading coefficient =a, degree=m

b) Leading coefficient =a, degree=m+n

c) Leading coefficient =a+b, degree=m

d) Leading coefficient =a+b, degree=m+n
