Find a if (ax3 + 3x2 - 3) and (2x3 - 5x + a) when divided by (x-4) leave same rmainder?  Choose the correct choice from the following answers: A) 1 B) 3 C) 4 D) 5 E) 6
remainders are,   R1 = f(4) = a(4)3+ 3(4)2-3= 64a+45   R2 = f(4) = 2(4)3- 5(4) + a= a +108   Since R1= R2   64a +45= a+108 =&gt; 63a = 63 =&gt; a =1   1
