Question

Q1) The polynomials k x3 + 3 x2 - 13 and 2 x3 - 5 x +k when divided by (x +2) leave the same remainder in each case. Find the value of k.

Q2) Factorise the following using Factor theorem, x3 + 13x2 + 32x + 20. (Note:- x3 , x2 stands for cube of x and square of x, so read accordingly)​

Answer 1

Answer:

Question 1

x+2 =x-2

Put the value - 2 on the place of x- 2X3, 3X-2X2-13, 2X-2X3-5X-2+k

Solve it = - 6+-12-3+-12+-10+k

-43+k

k= 43
