Answer 1

Answer:

Value of a = -1

Step-by-step explanation:

Solution:

To Find:

Value of a

---------------------------

Method:

When you divide a polynomial f(x) by (x - c) the remainder is f(c).

Let the polynomials be f(x) and g(x)

x - 3 = 0 => x = 3

f(3) = a * 3^3 + 4 * 3^2 + 3 * 3 - 4 = 27a + 41

g(3) = 3^3 - 4 * 3 + a = 15 + a

=> f(3) = g(3)

27a + 41 = 15 + a

26a = -26

a = -1

Hence,

Value of a = -1
