Answer 4

quotient will be degree 3 Ax^3 + Bx^2 + Cx +D
hence 4x^4 -15x^2 - 4 = (x -2)(Ax^3 + Bx^2 + Cx +D) [expand RHS]

4x^4 -15x^2 - 4 =Ax^4 + Bx^3+ Cx^2 +Dx -2Ax^3 -2Bx^2 -2Cx - 2D
[group and factor]

4x^4 -15x^2 - 4 =Ax^4 +(B-A)x^3 +(C-2B)x^2 +(D-2C)x - 2D
[equate coefficients]
4x^4 = Ax^4 A=4
(B-A) = 0 [no degree 3 coefficients] so B = 4
(C-2B) =-15 C= -7

- 2D = -4 D = 2

Hence answer = (4x^3 + 4x^2 -7x +2)
