Question

19.) The polynomials (ax³ + 3x ²- 3) and (2x³ - 5x + a) when divided by
(x-4) leave the same remainder. Find the value of a

please answer​

Answer 1

Step-by-step explanation:

ax^3+3x^2-3=2x^3-5x+a

a*4*4*4+3*4*4-3=2*4*4*4-5*4+a

a*64+48-3=128-20+a

64a+45=108+a

64a-a=108-45

63a=63

a=63/63

a=1
