Question

Q1) Using Remainder Theorem, find the remainder when

(i) f(x) = 5(x)^3 – 10(x)^2- 15x + 7 is divided by (x + 1)

(ii) f(x) = 8(x)^3 – 16(x)^2 + 14x – 5 is divided by (2x – 1)

(iii) f(x) = 8(x)^2 – 2x – 15 is divided by (2x + 3)

Q2) When x3 + 3(x)^2 – kx + 4 is divided by (x + 2), the remainder is k , find the value of k.​

Answer 1

the remember is k the value of k is 25
