59. If h(x) = f(x) - g(x), where f(x) = 5x2 + 15x - 25 and g(x) = 5x2 - 6x - 11, then h(x) is always divisible by which of the following ?

Answer and Explanation

Your Answer is

Correct Answer is C

Explanation

h(x)=5x2+15x-25-5x2+6x+11=21x-14=7(3x-2) then h(x ) must be divisible by 7, so choose C
