Answer:

24.   if we put x=2 in x³+2x²-5ax-8 it will give reminder p

2³+2*2²-5a*2-8 = p

8+8-10a-8=p

8-10a=p      ...(1)

similarly

3³-a*3²-12*3-6 = q

27-9a-36-6=q

-9a-15=q        ...(2)

given q-p=10     ...(3)

subtract (1) from (2)

-9a-15-(8-10a)=q-p

-9a+10a-15-8=10       (from (3))

a-23=10

a=33
