Q3 The polynomial p(x)=2x^3+kx^2-3x+5 and q(x)=x^3-2x^2-x+k,when divided by (x-2) leave the remainders r1 and r2 respectively...Find the value of k if r1=r2.


Q4 Find the value of k for which x-1 is a factor of the polynomial x^3-kx^2-11x-6 is ?

Answer 1

Answer:

Step-by-step explanation:

Factors of (2x - y)³ + (4z - 2x)³ +(3y - 4z)³ is 3 (2x - y) (4z - 2x)(3y - 4z) and the value of k in the polynomial p(x) = 2x³ + kx² - 3x + 5 and q(x)= x³ -2x² -x + k is -19/3 and the value of k in the polynomial x³ - kx² - 11x - 6 is - 16 .

SOLUTION of these questions is in the attachment .
