Question

the polynomial ax³+3x²-13and 2x³-5x+a, when divided by (x-2) leaves same remainder. find thr value of a​

Answer 1

Answer:

by x-2= 0 this implies x = 2

put this in both of equation

then the remainder of both the equations are same....

a(2)³ +3(2)² -13 = 2(2)³ -5(2) +a

8a +12 -13 = 16 -10 +a

7a = 6 +1 = 7

this implies a = 1
