If a polynomial f(x) is divided by x+a, remainder is given by f(-a).
Given,
a×(-1)^3 + 3×(-1)^2 - 13 = 5×(-1)^3 - 8×-1 + a
2a = -13
a = -6.5
Given,
a×(-1)^3 + 3×(-1)^2 - 13 = 5×(-1)^3 - 8×-1 + a
2a = -13
a = -6.5

are you sure it is correct, because i have to write it in my project file
100% sure
But instead of 6.5 can we write 13/2
