Question

16. If 2 is the zero of both the polynomials 3x2 + mx – 14 and 2x3 + nx2 + x - 2, then the value of
m - 2n is equal to
(1) 6
(2) 7
(3) 8
(4) 9​

Answer 1

Answer:

The answer is 10 so this means that the options are not correct as the value of m is equal to 4 and n is equal to -3 so m -2n is equal to 4 -(-3*2) 4-(-6) = 4+6=10
